Important Scientific Instruments and their Uses


Hello Readers!
In this post we are sharing List of few important Scientific Instruments and their uses. These instruments are frequently asked in different competitive exams like Railways, SSC, Banking, PSUs etc. We hope this will be very much helpful to your upcoming competitive exams. If you find any Instrument which is not there please comment below , we will update this post with those instruments.

List Of Important Scientific Instruments:

Accumulator : Electrical energy is stored.

Altimeter : Used in aircraft for measuring altitudes.

Ammeter : Measuring the electrical current in amperes.

Anemometer : Measuring the strength of winds.

Audiometer : Measuring intensity of wind.

Audio phone : It is used for improving imperfect sense of hearing.

Barometer : Measuring atmospheric pressure.

Binocular : An optical instrument designed for magnified view of distant 
objects by both eyes simultaneously.

Cardiogram : For recording the heart movements.

Calorimeter : Measuring of quantities of heat.

Chronometer : A clock that keeps very accurate time as the one that is used 
to determine longitude at sea.

Colorimeter : An instrument for comparing intensities of colour.

Commutator: An instrument to change or remove the direction of an electric current, in dynamo used to convert alternating current into direct current.

Cyclotron : Studying the properties of atoms by smashing them.

Dynamo : A device for converting mechanical energy into electrical energy.

Dynamometer :An instrument for measuring the electrical power.

Electroscope : An instrument for detecting the presence of electric charge.

Galvanometer : For detecting and measuring electric current.

Phonograph : For reproducing sound.

Quartz Clock :A highly accurate clock used in astronomical observations and other precision work

Radar : Radio, angle, detection and range is used to detect the direction and 
range of an approaching aeroplane by means of radio micro waves.

Radiometer : An instrument for measuring the emission of radiant energy

Radio Micrometer : An instrument for measuring heat radiations

Rain Gauge: An instrument for measuring rainfall

Rectifier : An instrument used for the conversion of AC into DC.

Refractometer: An instrument used to measure the refractive index of a substance

Resistance Thermometer : Used for determining the electrical resistance of conductors

Salinometer: A type of hydrometer used to determine the concentration of salt solutions by measuring their densities

Seismometer (Seismograph) : An Apparatus for measuring and recording earthquake shock

Sextant : For guiding ships or surveying land.

Spectroscope: An instrument used for spectrum analysis

Speedometer : It registers the speed at which the vehicle is moving
