Analog Comparators

(80 companies)
Analog comparators are amplifiers that compare the magnitude of voltages at two inputs. An analog comparator is an operational amplifier with negative feedback removed, and with no feedback and very high gain, the output voltage goes to one extreme to the other.

VU Meters

(10 companies)
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

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

Milliohm Meters

(75 companies)
Milliohm meters are capable of measuring very small resistances

Phase Meters

(68 companies)
Phase meters (phase testers, phase rotation meters) check the phase sequence and phase orientation in three-phase electrical systems.

Gas Flow Meters

(420 companies)
Gas flow meters are used for measuring the flow or quantity of a moving gas in an enclosed pipe or passage.

LCR Meters

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

Utility Meters

(127 companies)
Utility meters are used to monitor the consumption of water, gas or electricity by businesses or residences.

Power Meters

(385 companies)
Power meters are used for high-accuracy measurements of power over a wide-frequency bandwidth, and from both AC and DC circuits.
Lux meters quantify the intensity of a light source, as perceived by the human eye, in foot-candles (fc) or lux (lx).

KVA Meters

(48 companies)
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.

IC Analog Multiplexers

(73 companies)
Analog multiplexers have sets of switches that connect several analog inputs to a common analog output, allowing a single analog-to-digital converter (ADC) to sample data from multiple inputs.

Noise Meters

(19 companies)
RF noise meters are used to measure and/or monitor noise produced by RF equipment.

SWR Meters

(9 companies)
SWR meters are used to measure the standing wave ratio (SWR) in radio equipment. They are sometimes called VSWR meters.
Energy meters measure the total energy of a single pulse and optical power meters measure the average power of a continuous light beam.
