Lux meters or light meters measure illumination in terms of luxes (lx) or foot candles (fc

Utility meters are used to monitor the consumption of water, gas or electricity by businesses or residences

Sound level meters and noise dosimeters are used in sound and noise analysis. Applications include industrial safety, traffic noise studies, and scientific noise measurement

LCR meters and impedance meters measures inductance (L), capacitance (C), and resistance or impedance (R

Capacitance meters measure the value of capacitance in circuit elements

KVA meters measure the apparent power of AC devices in kilovolt-amperes (KVA). Apparent power is the combination of a circuit’s true power and reactive power

Frequency meters are instruments that provide analog outputs as frequencies that vary as a function of the applied input. They display values on a dial, usually with a needle or moving pointer

Analog dBm meters are instruments that measure signal power. They display values on a dial, usually with a needle or moving pointer

Analog resistance meters are instruments that measure electrical resistance. They display values on a dial, usually with a needle or moving pointer

Power meters are used for high-accuracy measurements of power over a wide-frequency bandwidth, and from both AC and DC circuits.

Digital resistance meters are instruments that measure electrical resistance. They use solid-state components and display values digitally

BTU meters measure the energy changes in liquid or gas flows in British thermal units (BTU

Electrostatic meters measure voltage, field and charge without transferring the charge to the instrument. As a result, it is unnecessary to modify parameters due to changing loads

VU meters measure the volume (intensity) of analog audio signals. They display signal levels in volume units (VU), a measure of average volume level

S meters (strength meters, signal-strength meters) measure the strength of signals in communication systems such as receivers and transmitters
