Scientific Instruments and their uses

Do you know the name of scientific instrument? What type of these are? What are the uses? If you don’t know lets go through out the post where you will get name of all important scientific instruments and their uses in our life, for business purpose or for technical solution purpose. Altimeter Measures altitudes (Used in aircraft) Ammeter Measures strength of electric current Anemometer Measures force and velocity or wind and directions Audiometer Measures intensity of sound Barograph Continuous recording of atmospheric pressure Barometer Measures atmospheric pressure Binoculars To view distant objects Bolometer To measure heat radiation Callipers Measure inner and outer diameters of bodies Calorimeter Measures quantities of heat Cardiogram(ECG) Traces movements of the heart ; recorded on a Cardiograph Cathetometer Determines heights, measurement of levels, etc, in scientific experiments Chronometer Determines longitude of a vessel at sea Colorimeter Compares intensity of colours Commutator To change / reverse the direction of electric current; Also used to convert AC into DC Cryometer A Type of thermometer used to measure very low temperatures, usually close to 0`C Cyclotron A Charged particle accelerator which can accelerate charged particles to high energies Dilatometer Measures changed in volume of substances Dyanamo To Covert mechanical energy into electrical energy Dynamometer Measure electrical power Electronecephalo Records and interprets the electrical waves of the Graph(EEC) Brain (brain waves ) recorded on electroence phalograms Electrometer Measures very small but potential difference in electric currents Electroscope Detects presence of an electric Charge Eletromicroscope To obtain a magnifying view of very small objects capable of magnifying up to 20,000 times Endoscope To examine internal parts of the body Fathometer Measures depth of the flux Fluxmeter Measures magnetic flux Galvanometer Measures electric current Hydrometer Measures the relative density of liquids Hygrometer Measure level of humidity Hydrophone Measure sound under water Hygroscope Shows the changes in atmospheric humidity Hypsometer To determine boiling point of liquids Hymograph Graphically records physiological movement. (e.g.…..,blood pressure/heartbeat) Lactometer Measures the relative density of milk to determine purity Machmeter Determines the speed of an aircraft in terms if the speed of sound Manometer Compares magnetic movement and fields Manometer Measures the pressure of gases Micrometer Coverts sound waves into electrical vibrations Microphone Measure distances /angles Microscope To obtain a magnified view of small objects Nephetometer Measures the scattering of light by particles suspended in a liquid Ohmmeter To measures electrical resistance in objects Ondometer Measures the frequency if electromagnetic waves, especially in the radio-frequency band Periscope To view objects above sea level (Used in submarines) Photometer Compares the luminous intensity of the source of light Polygraph Instrument that simultaneously records changed in physiological processes such as heartbeat, blood pressure the respiration used a lie detector Pyknometer Determines the density and coefficient of expansion of liquids Pyrometer Measures very high temperature Quadrant Measures altitudes and angles in navigation and astronomy Radar To detect the direction and ranges of an approaching aeroplane by means of radiowaves, ( Radio, Angle ,Detection and Range ) Radio Micrometer Measures heat radiation Refractometer Measures salinity of solutions Sextant Used by navigators to find the latitude of place by measuring the elevation above the horizon of the sun or another star; also used to measure the height of very distant objects Spectrometer Spectroscope equipped with calibrated scale to measure the position of spectral lines (Measure of Refractive indices) Spherometer Measures curvature of spherical objects Tachometer To determine speed, especially the rotational speed of a shaft (Used in aeroplanes and motor-boats) Tangent galvanometer Measure the strength of direct current Telemeter Records physical happenings at a distant place Telwprinter Receives and sends typed messages from one place to another Telescope To view distant objects in space Thermometer Measure Temperature Thermostat Regulates temperature at a particular point Tonometer To measure the pitch of a sound Transponder To receive a signal and transmit a reply immediately Udometer Rain gauge Ultrasonoscope To measure and use ultrasonic sound (beyond hearing use to make a Ecogram to detect brain tumours, heart defects and abnormal growth Venturimeter To measure the rate of flow of liquids Vernier Measures Small sub-division of scale Viscometer Measures the viscosity of liquid Voltmeter To measure electric potential difference between two points Wattmeter To measure the power of an electric circuit Wavemeter To measure the wavelength of a radiowave
