Biometric devices are used for security and authentication purposes. They are used to authenticate and recognize fingerprints, the retina/iris, faces, hand geometries, and others.
Current sensors measure AC and/or DC current levels. They receive current inputs and provide outputs as analog voltage signals, analog current levels, switches, or audible signals.
Digital ammeters are instruments that measure current flow in amperes and display current levels on a digital display. These devices provide information about current draw and current continuity in order to help users troubleshoot erratic loads and trends
Digital multimeters (or multi-meters) are used to measure electrical quantities such as voltage, current, resistance, frequency, temperature, capacitance, and time period measurements.
Digital resistance meters are instruments that measure electrical resistance. They use solid-state components and display values digitally.
Digital voltmeters are instruments that measure voltage or voltage drop in a circuit. They use solid-state components and display values digitally.
Electrical capacitance sensors detect and measure capacitance, the charge storage capacity of an electronic component.
Electrical charge sensors measure electrical charge.
Electrical field strength sensors are used to measure the strength of electrical fields.
Electrical inductance sensors measure the inductance of an electrical component or system.
Electrical power sensors are used to measure electric power.
Electrical resistance and electrical conductance sensors measure the resistance or conductance of an electrical component or system.
Electrical voltage sensors measure AC and/or DC voltage levels. They receive voltage inputs and provide outputs as analog voltage signals, analog current levels, switches, or audible signals.
Electrometers are instruments that measure electric charge and/or electric potential difference.
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.
EMF meters detect and monitor harmful electric, magnetic or electromagnetic fields surrounding personal or work areas.
Receivers are used to detect buried or hidden piping, equipment or ferromagnetic ores.
Frequency counters are digital indicating meters for accurate measurement and display of square wave and pulse input signals.
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.
Gaussmeters are instruments designed to measure extremely high level magnetic fields.
Ground resistance testers are devices that are used to measure and test electrical grounding systems. Grounding enables optimum electrical continuity between conducting objects and earth.
Harmonic distortion meters are instruments that measure harmonic distortion or phase position.
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.
LCR meters and impedance meters measures inductance (L), capacitance (C), and resistance or impedance (R).
Magnetic field instruments include meters, gauges, recorders and other instrumentation for the measurement of magnetic fields and/or magnetic flux.
Magnetic field sensors measure magnetic field strength, direction, and/or magnetic flux. They are used for scientific measurement, navigation, and industrial applications.
Magnetometers are scientific instruments that measure the strength and/or direction of a magnetic field. There are two basic types: scalar and vector.
Megohmmeters generate high voltage, low current signals for testing the breakdown strength of electrical insulation. They are called megohmmeters because the insulating resistance of a properly designed product is expressed in mega ohms (M ).
Milliohm meters are capable of measuring very small resistances
RF noise figure meters measure the noise contribution of an amplifier relative to a noise-free amplifier at a reference temperature. Usually expressed in dB for Ku-band amplifiers.
Phase meters (phase testers, phase rotation meters) check the phase sequence and phase orientation in three-phase electrical systems.
Potentiostats and galvanostats are electrochemical instruments used in electrochemistry, battery and fuel cell testing, corrosion control, voltammetry, biomedical research, surface imaging, and related applications.
Power meters are used for high-accuracy measurements of power over a wide-frequency bandwidth, and from both AC and DC circuits.
S meters (strength meters, signal-strength meters) measure the strength of signals in communication systems such as receivers and transmitters.
SWR meters are used to measure the standing wave ratio (SWR) in radio equipment. They are sometimes called VSWR meters.
VU meters measure the volume (intensity) of analog audio signals. They display signal levels in volume units (VU), a measure of average volume level.
