Top 25 Scientific Instruments

1. What is an ammeter?

The instrument used to measure Electric current is known as ammeter.

2. What is an Altimeter?

Altimeter is a meter used to find the altitude of an Aircraft flying, when it is flying.

3. What is an Anemometer?

This is an instrument for measuring the speed or power of the wind.

4. Which equipment is used to determine the depth of the sea?

Fathometer is used to determine the depth of water in sea

5. What is lactometer?

To find the purity of Milk we used Lactometer

6. What is a Magnetometer?

It is an instrument used to measure the strength of a magnetic field or the strength of magnets.

7. What is a magnetic Amplifier?

It is an instrument consisting of two coils of wire wound round an iron core. One coil carries the direct current (control coil) and the other alternating current. A small change in the control coil changes the magnetization of the core and allows a larger current to flow through the other coil.Hence a small change in current is amplified in the second coil.

8. What is a Dynamometer?

It is an instrument to measure the forces. Eg, the strength of the muscles of hand, or horse power of an engine.

9. What is a dosimeter?

It is an instrument to measure the amount or raiation absorbed by a person over a period of time.

10. What is an Eudiometer?

This is an instrument for measuring the changes in volumes of gases when they act chemically. So called because it was first used to measure oxygen or good gas.

11. What is a Hydrometer?

It is a devise to measure the moisture in atmosphere.

12. What is a pyrometer?

An instrument to measure very high temperatures.

13. What is a radiometer?

To measure the intensity of light we use radiometer.

14. What is a Seismograph?

It is an instrument used to show earthquakes , movement of the surface of the earth. The needle of the instrument draws a wavy line showing each pressure wave.

15. What is a spectrometer?

It is a device to measure the refractive index of light.

16. What is an Odometer?

It is a meter which determines the number of revolutions of a moving wheel

17. What is a Techameter?
