2.  An ammeter is a measuring instrument used to measure the
current in a circuit.
 Electric currents are measured in amperes (A), hence the name.
 Instruments used to measure smaller currents, in the milli ampere
or microampere range, are designated as milli ammeters or micro
ammeters

3.  A barometer is a scientific instrument used in meteorology to
measure atmospheric pressure.
 Pressure tendency can forecast short term changes in the weather.
 Numerous measurements of air pressure are used within surface
weather analysis to help find surface troughs, high pressure systems
and frontal boundaries.
2. Barometerair pressure

4. 3. Clock A clock is an instrument to indicate, keep, and co-ordinate time.
 The word clock is derived ultimately from the Celtic
words clagan and clocca meaning "bell".
 In general usage today a "clock" refers to any device for measuring and
displaying the time.
 Watches and other timepieces that can be carried on one's person are
often distinguished from clocks

5. 4. Dynamometerforce, torque or power
 A dynamometer or "dyno" for short, is a device for measuring
force, torque, or power.
 For example, the power produced by an engine, motor or
other rotating prime mover can be calculated by
simultaneously measuring torque and rotational speed (RPM).

6. electric charge
5. Electrometer
 An electrometer is an electrical instrument for measuring electric
charge or electrical potential difference.
 There are many different types, ranging from historical handmade
mechanical instruments to
high-precision electronic devices.

7. 6. frequency counterfrequency of alternating current
A frequency counter is an electronic instrument, or component of one,
that is used for measuring frequency.
Frequency counters usually measure the number of oscillations or pulses
per second in a repetitive electronic signal.
Such an instrument is sometimes referred to as a Cytometer, particularly
one of Chinese manufactures

8. 7. Galvanometer
 A galvanometer is a type of sensitive ammeter: an
instrument for detecting electric current.
 It is an analog electromechanical actuator that produces a
rotary deflection electric current through its coil in a
magnetic field.
electricity

9. 8. Hydrometer
 A hydrometer is an instrument that measures the specific gravity
(relative density) of liquids.
 The ratio of the density of the liquid to the density of water.
 A hydrometer is usually made of glass, and consists of a cylindrical
stem and a bulb weighted with mercury or lead shot to make it float
upright.
density of the liquid

10. 9. Inclinometerangle of a slope
 A device for measuring the angle of inclination of something,
especially from the horizontal.
 An inclinometer or clinometer is An instrument for
measuring angles of slope (or tilt), elevation or depression of
an object with respect to gravity

11. 10. katharometercomposition of gases
 The thermal conductivity detector (TCD), also known as
a Katharometer, is a bulk property detector and a chemical specific
detector 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.

12. 11. load cellmeasurement of force
 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 types of load cell sinclude hydraulic load cells,
pneumatic load cells and strain gauge load cells.

13.  An instrument designed to measure electric current, voltage, and
usually resistance, typically over several ranges of value.
 A multimeter is used to make various electrical measurements, such as
AC and DC voltage, AC and DC current, and resistance.
12. Multimeter
electrical potential, resistance, and current

14.  A nephelometer is an instrument for measuring concentration of
suspended particulates in a liquid or gas colloid.
 A nephelometer measures suspended particulates by employing a
light beam (source beam) and a light detector set to one side
(often 90°) of the source beam.
13. Nephelometer
particle in a liquid

15.  An ohmmeter is an electrical instrument that measures
electrical resistance, the opposition to an electric current.
14. Ohmmeterelectrical resistance

16.  A pyrometer is a type of remote-sensing thermometer used to
measure the temperature of a surface.
 Various forms of pyrometers have historically existed.
15. Pyrometerhigh temperature

17.  A Quartz Crystal Microbalance (QCM) measures a mass variation
per unit area by measuring the change in frequency of a quartz
crystal resonator.
 The resonance is disturbed by the addition or removal of a small
mass due to oxide growth/decay or film deposition at the surface
of the acoustic resonator.
16. Quartz Crystal Microbalance
thickness of deposited thin film

18.  A radiometer or roentgenometer is a device for measuring
the radiant flux (power) of electromagnetic radiation.

17. Radiometer

19. 18. SWR meterstanding wave ratio
 The SWR Meter or VSWR (voltage standing wave ratio)
meter measures the standing wave ratio in a transmission
line.

20. 19. Tachometer
 A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an
instrument measuring the rotation speed of a shaft or disk, as in a
motor or other machine.
 The device usually displays the revolutions per minute (RPM) on a
calibrated analogue dial, but digital displays are increasingly common.
rotation speed of a shaft

21. 20. UV Meter
 "Ultraviolet" means "beyond violet" (from Latin ultra,
"beyond"), violet being the colour of the highest frequencies of
visible light. Ultraviolet light has a higher frequency than
violet light.
ultraviolet light

22. 21. Voltmeterelectric potential, voltage
 A voltmeter is an instrument used for measuring electrical potential difference
between two points in an electric circuit.
 Analog voltmeters move a pointer across a scale in proportion to the voltage of the
circuit; digital voltmeters give a numerical display of voltage by use of an analog to
digital converter.
 The voltmeter in a circuit is represented by encircled 'V'.

23. electrical power
22. Wattmeter
 It is an instrument for measuring the electric power (or the supply rate
of electrical energy) in watts of any given circuit.
 Electromagnetic wattmeter's are used for measurement of utility
frequency and audio frequency power; other types are required for
radio frequency measurements.

24.  An instrument for ascertaining the degree
of fermentation occasioned by the mixture of different liquids
and the degree of heat which they acquire in fermentation.
