ELECTRONIC TUNER: The clip-on tuner was invented in1995 by mark Wilson of Onboard Research corporation, which marketed it as The Intellitouch Tuner Model PT1. In music, an electronic tuner is a device that detects and displays the pitch of musical notes played on a musical instrument. “Pitch” is the highness or lowness of a musical note, which is typically measured in Hertz. Simple tuners indicate typically an analog needle-dial, LEDs, or an LCD screen- whether a pitch is higher, lower, or equal to the desired pitch.
ELLIPSOMETER: P. Drude {1863-1906} was the first to build an ellipsometer even before Rothen has coined the word ‘ellipsometry’ in 1945. The equipment built by Drude is surprisingly very similar to many types of instrument in use today. Ellipsometer measures the change of polarization upon reflection or transmission and compares it to a model. It can be used to characterize composition, roughness, thickness {depth}, crystalline nature, doping concentration, electrical conductivity and other material properties.
EUDIOMETER: In 1775, marsilio Landriani invented the first eudiometer and used it to conduct his own experiments. The eudiometer is a laboratory device that measures the change in the volume of a gas mixture following a physical or chemical change.
EVAPORIMETER: The evaporimeter was invented by a French Monsieur Albert Piche in the year 1907. The evaporimeter is a scientific instrument used for measuring the rate of water evaporation from a wet surface to the atmosphere. Atmospheres are mainly used by farmers and growers to measure evapotranspiration {ET} rates of crops at any field location.
FATHOMETER: Herbert Grove Dorsey {April 24, 1876-1961} was an American engineer, inventor and physicist. He was the principal engineer of the United States coast and Geodetic survey Radio sonic Laboratory in the 1930s. He invented the first practical fathometer, a water depth measuring instrument for ships. So, therefore, the major use of a fathometer is for determining water depth.
FEELER GUAGE: A feeler gauge is a tool used to measure gap widths. Feeler Gauge is mostly used in engineering to measure the clearance between two parts.
They consist of a number of small lengths of steel of thickness with measurement marked on each piece. They are flexible enough that, even if they are all on the same hinge, several can be stacked together to gauge intermediate values. It is common to have two sets for imperial units {typically measured in hundredths of a millimeter} measurements. The same device with wires of specific diameter instead of flat blades is used to set the gap in spark plugs to the correct size; this is done by decreasing or increasing the gap until the gauge of the correct size just fits inside the gap.
INCLINOMETER: Gravity inclinometer –one of the most practical gravity inclinometer was invented by William B. Melick in the year 1889. An inclinometer is an instrument used for measuring angles of slope {or tilt}, elevation, or respect to gravity’s direction.

It was patented in 1819 by Silas Hawes, a blacksmith from south Shaftsbury, Vermont. Although Albert J.Swason invented a speed square in 1925 as a carpenters layout tool. He later founded Swason Tool Company, inc. to produce it. Today Swason Tool Company still manufactures and distributes the speed square and other carpentry tool from its headquarters in Frankfort, Illinois.

This framing square can be used as a straight-edge, finding and establishing right angles and marking cut-off work on wide stock.

FREQUENCY TRANSMISSION: Gugliemo Marconi, was an Italian inventor and electrical engineer, known for his pioneering work on long distance radio transmission. A frequency counter transmission is an electronics instrument, or component of one, that is used for measuring frequency. Frequency counters usually measure the number of cycles of oscillations, or pulse per second in a periodic electronic signal.
FUEL GUAGE: In 1917, John Gilbert Collison invented the dashboard gas gauge and took the idea to General Motors Co. in 1920.

In automobile and aircrafts engineering, a fuel gauge or gas gauge is an instrument used to indicate the amount of fuel in a fuel tank. As used in vehicles, the gauge consists of two parts namely;

The sending unit – in the tank

The indicator – on the dashboard

The sending unit usually uses a float connected to a potentiometer, typically printed ink design in a modern automobile. As the tank empties, the float drops and slides a moving contact along the resistor, increasing its resistance. In addition, when the resistance is at certain point, it will also turn on a ‘low fuel’ light on some vehicles.

Meanwhile, the indicator unit {usually mounted on the dashboard} is measuring and displaying the amount of electric current flowing through the sending unit. When the tank level is high and maximum current is flowing, the needle points to “F” indicating a full tank. When the tank is empty and the least current is flowing, the needle points to “E” indicating an empty tank.

GALVANOMETER: The earliest galvanometer was invented by Johann Schweigger at the University of Halle on the 16th September 1820. Andre –Marie Ampere also contributed to its development. Early designs increased the effect of magnetic field generated by the current by using multiple turns of wire. A galvanometer is an electrochemical instruments used for detecting and indicating an electric current. A galvanometer works as an actuator, by producing a rotary deflection {of a “pointer”}, in response to electric current flowing through a coil in a constant magnetic field. Early galvanometers were not calibrated but their later developments were used as a measuring instrument, called ammeters, to measure the current flowing through an electric circuit.

PYCNOMETER: In the year 1967, Edward Y.H. Keng invented an instrument which he called “helium pycnometer”. The first U.S. patent on this invention was issued in 1969. A gas pycnometer is a laboratory device used for measuring the density – or, more accurately, the volume- of solids, be they regularly shaped, porous or non-porous, monolithic, powdered, granular or in some way comminuted, employing some method of gas displacement and the volume: pressure relationship known as boyles law. A gas pycnometer is also known as helium pycnometer.

GEIGER COUNTER: The German physicist Hans Wilhelm Geiger is best known as the inventor of the Geiger counter to measure radiation. In 1908, Geiger introduced the first successful detector individual alpha particles. Later versions of this counter were able to count beta particles and other ionizing radiation.

The Geiger counter is used to measure the amount of ionizing radiation available in a certain area. It can detect alpha particle and beta particles, as well as gamma rays, because of the ionization that occurs in the tube of the instrument. It’s one of the world’s best known radiation instruments and was invented in 1928 by Hans Geiger and Walther Muller.

GLUCOMETER: The first glucose meter was invented by Anton Hubert {Tom} Clemens with the patent issued on the 14th of September 1971.

A glucose meter is a medical device for determining the appropriate concentration of glucose in the blood. It can also be a strip of glucose paper dipped into a substance and measured to the glucose chart.

GRAPHOMETER: Philippe Danfrie invented the graphometer in the year 1597 and the term graphometer was popular with French geodesists. The graphometer is a surveying instrument used for angle measurements. It consists of a semicircular limb divided into 180 degrees and sometimes subdivided into minutes. The limb is subtended by the diameter with the two sights at its ends. In the middle of the diameter a “box and needle” {compass} is fixed.
HELIOMETER: The heliometers is the most notable discovery that happened in 1838, when a German astronomer Friedrich Bessel used a heliometers designed by German physicist Joseph Von Fraunhofer to perform the first measurement of the parallax, and hence the distance, of a star from earth. Heliometers is an instrument originally designed for measuring the variation of the suns diameter at different seasons of the year, but applied now to the modern form of the instrument which is capable of much wider use.

INKOMETER: An inkometer is a specialized measuring instrument used by printing industry to measure the “tack” {adhesiveness} of an ink with the roller system on an offset press. The importance of tack is that it is not so excessive that it doesn’t allow effective transfer from the rollers to the plate and then to the blanket and onto the substrate being printed. Inks can also be tack “graded” in descending sequence to allow for better trapping of one color over another. Inks with too much tack can cause the surface of the paper to pick off and interfere with transfer on subsequent printing unit and copies. The amount of tack can be controlled by changing the amount of solvent or other diluents used in the ink.

INFRARED THERMOMETER: In 1714, Dutch scientist and inventor Daniel Gabriel Fahrenheit invented the first reliable thermometer, using mercury instead of alcohol and water mixtures. In 1724 he proposed a temperature scale which now {slightly adjusted} bears his name. He could do this because he manufactured thermometers using mercury {which has a high coefficient of expansion} for the first time and the quality of his production could provide a finer scale and greater reproducibility, leading to its general adoption. In 1742, Anders Celsius {1701-1744} proposed a scale with zero at the boiling point and 100 degrees at the freezing point of water, though the scale which now bears his name has them the other way around. French entomologist Rene Antoine Ferchault de Reaumur invented an alcohol thermometer and temperature scale in 1730 that ultimately proved to be less reliable than Fahrenheit’s mercury thermometer. The first physician that put thermometer measurement to clinical practice was Herman Boerhaave {1668-1738}. In 1886, Sir Thomas Clifford Allbutt {1836-1925} invented a clinical thermometer that produced a body temperature reading in five minutes as oppose to twenty. In 1999, Dr. Francesco Pompei of the Exergen Corporation introduced the world’s first temporal artery thermometer, a non-invasive temperature sensor which scans the forehead in about two seconds and provides a medically accurate body temperature.

KATHAROMETER: The katharometer was invented in 1878 by the American astronomer Samuel Pierpont Langley. The thermal conductivity detector {TCD}, also known as katharometer, is a bulk property detector and a chemical specific detector. They are commonly used in gas chromatography. This detector senses changes in the thermal conductivity of the column effluent and compares it to a reference flow of carrier gas. Since most compounds have a thermal conductivity much less than that of the common carrier gases of helium or hydrogen, when an analyte elutes from the column the effluent thermal conductivity is reduced, and a detectable signal is produced.

LACTOMETER: an instrument invented by Mr. Dicas, of Liverpool, for the purpose of ascertaining the different qualities of milk from its specific gravity compared with water. On this subject Dr. Ure observes, that it is not possible to infer the quality of milk from the indication merely of specific gravity instrument, because both cream and water affects the specific gravity of milk alike.

LIGHT METER: Oliver B. Shallenberger invented the watt-hour meter. On 14th august 1888 in Pittsburg, Pennsylvania, Oliver B. Shallenger received a patent for the watt-hour meter, a device that measured the amount of A.C. current and made possible the business model of the electric utility. A light meter is often used to determine the proper exposure for a photograph. Typically a light meter will include either digital or analog electronic circuit, which allows the photographer to determine which shutter speed and f-number given a certain lighting situation and film speed. Light meters are also used in the fields of cinematography and scenic design, in order to determine the optimum light level for a scene. They are used in the general field of architectural lighting design to verify proper installation and performance of a building lighting system, and in assessing the light levels for growing plants.

LOAD CELL: In 1843 an English physicist called Sir Charles Wheatstone popularized the “Wheatstone bridge” by creating a devise bridge circuit that could measure electrical resistance. A load cell is a transducer that is used to create an electrical signal whose magnitude is directly proportional to the force being measured. The various load cell types includes hydraulic, pneumatic, and strain gauge. Strain gauge load cells are the most common in industry. These load cells are particularly stiff, have very good resonance values, and tend to have long life cycles in application. Strain gauge load cells work on the principle that the strain gauge {a planar resistor} deforms when the material of the load cells deforms appropriately. Deformation of the strain gauge changes its electrical resistance, by an amount that is proportional to the strain. The change in resistance of the strain gauge provides an electrical value change that is calibrated to the load placed on the load cell.

MAGNETOMETER: the first magnetometer is capable of measuring the absolute magnetic intensity was invented by Carl Friedrich Gauss in 1833 and notable developments in the 19th century included the Hall Effect, which is still widely used. Magnetometers are widely used for measuring the earth’s magnetic field and in geophysical survey to detect magnetic anomalies of various types. They are also used in military to detect submarines. Consequently, some countries, such as the United States, Canada and Australia, classify the more sensitive magnetometers as military technology, and control their distribution. Magnetometers can be used as metal detectors; they can detect only magnetic {ferrous} metals, but can detect such metals at a much larger depth than conventional metal detectors; they are capable of detecting large objects, such as cars, at tens of metres, while a metal detectors range is rarely more than 2 metres.

PRESSURE GAUGE: Otton Von Guericke, {born nov. 20,1602, Magdeburg, Germany}- German physicist, engineer, and natural philosopher who invented the first air pump and used it to study the phenomenon of vacuum and the role of air in combustion and respiration. Pressure measurement is the analysis of an applied force by a fluid {liquid or gas} on a surface. Pressure is typically measured in units of surface area. Many techniques have been developed for the measurement of pressure and vacuum. An instrument used to measure and display pressure in an integral unit is called pressure gauges or vacuum gauges. A vacuum gauge is a pressure gauge used to measure pressures lower than the ambient atmospheric pressure.

MASS FLOW METER: the first mass flow meter patent dates back to the 1950s and the first coriolis mass flow meter were built in the 1970s. This flow meter artificially introduces coriolis acceleration into the flowing stream and measure mass flow by detecting the resulting angular momentum. A mass flow meter, also known as an inertial flow meter is a device that measures mass flow rate of a fluid traveling through a tube. The mass flow rate is the mass of the fluid traveling past a fixed point per time.

MASS SPECTROMETER: the mass spectrometer was invented by F.W. ASTON shortly after the World War 1. By 1927 Aston had built an instrument that was accurate to more than 1 part in 10,000, and mass spectrometry became the method of choice for measuring the relative mass of an atom or molecule. Mass spectrometry is used in many different fields and is used in many different fields and is applied to pure samples as well as complex mixtures. A mass spectrum is a plot of ion signal as a function of the mass-to-charge ratio. These spectra are used to determine the elemental or isotopic signature of a sample, the masses of particles and of molecules, and to elucidate the chemical structures of molecules and other chemical compounds.

PLANIMETER: The first of such instrument, employing a disk-and-wheel principle to integrate, was invented in 1814 by J.H. Hermann, a Bavarian engineer. Improved mechanisms were invented by the British mathematical physicist James Clerk Maxwell {1855} and the Scottish engineer James Thomson {1876}. So as is known, Maxwell never actually built a working model of his invention, which he called a platometer, but Thomson’s principle was not only adapted by his brother, the physicist William Thomson{later 1st Baron Kelvin}, for a machine used in harmonic analysis of tides. A practical, inexpensive polar polarimeter was invented by the Swiss mathematician Jacob Amsler about 1854. A planimeter, also known as platometer is measuring instrument used to determine the area of an arbitrary two-dimensional shape.

POLARIMETER: polarization by reflection was discovered in 1808 by Etienne-Louis Malus {1775-1812}. A polarimeter is a scientific instrument used to measure the angle of rotation caused by passing polarized light through an optically active substance. Some chemical substances are optically active, and polarized light will rotate either to the left or right when passed through these substances. The amount by which the light is rotated is known as angle of rotation. The angle of rotation is basically known as observed angle.

POTENTIOMETER: the slide wire potentiometer was invented by Johann Christian Poggendorff {1796-1877} in 1841. The measuring instrument called potentiometer is essentially a voltage divider used for measuring electric potential {voltage}; the component is an implementation of the same principle, hence its name. Potentiometers are commonly used to control electrical devices such as volume controls audio equipment.

PROFILOMETER: a profilometer is a measuring instrument used to measure a surface s profile, in order to quantify its roughness. Critical dimensions as step, curvature, flatness are computed from the surface topography.

QUADRANT: the quadrant was the first altitude measuring instrument developed for use in celestial navigation, dating back to the 15th century. Its first recorded use at sea was by Diego Gomez in 1461. A quadrant is a frame, traditionally square, used in ecology and geography to isolate a standard unit of area for study of the distribution of an item over a large area.

QUARTZ CRYSTAL MICROBALANCE: in 1956, Clark invented his oxygen-sensor based on a pt electrode; in 1959, the first piezoelectric mass deposition sensor {a quartz crystal microbalance} was produced. It is used for monitoring the rate of deposition in thin film deposition system under vacuum. In liquid, it is highly effective in determining the affinity of molecules to surfaces functionalized with recognition sites.
