Continuity testers are electrical test instruments that are used to determine if an electrical circuit exists between two points.
Current leakage testers measure the amount of current that leaks to ground.
Current testers and detectors check for the presence of current flow in electrical circuits. They are also used to locate current in hidden wires and cables
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 delay generators produce pulses at precise, programmed intervals to trigger devices under test. They are also used for gating, timing, triggering, and syncing.
Digital multimeters (or multi-meters) are used to measure electrical quantities such as voltage, current, resistance, frequency, temperature, capacitance, and time period measurements.
Digital panel meters measure and display processes and electrical variables via an alphanumeric digital readout.
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 safety testers are instruments used to test diverse electrical safety such as testing outlet polarity, line voltage level, ampere rating, medical equipment, and others.
Electric test probes are used to establish a connection between a circuit under test and the measuring instrument.
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.
EMC Testers are devices used to test or monitor parts and products for electromagnetic compatibility (EMC).
EMF meters detect and monitor harmful electric, magnetic or electromagnetic fields surrounding personal or work areas.
EMI and RFI testers monitor the presence of unwanted electromagnetic and radio frequency radiation.
Receivers are used to detect buried or hidden piping, equipment or ferromagnetic ores.
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.
Ground fault circuit interrupter (GFCI) testers are used to check for improper wiring conditions in GFCI devices such as electrical receptacles. They detect leakage currents that are smaller than those used in fuses and circuit breakers, but still large enough to cause harmful electric shocks.
Ground bond testers are electrical safety test devices that perform electrical compliance tests.
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.
Hipot testers are electrical safety test devices that perform a variety of electrical compliance tests.
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.
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.
Pulse generators are electrical test equipment used to generate pulses that are injected into devices under test in order to study the behavior of these devices.
Receptacle testers are used to test wiring in electrical receptacles.
RF power meters measure the strength of an RF signal in dBm or watts and may also be called an RF wattmeter. Typically RF power meters are used to measure the output of a transmitter.
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.
Voltage testers check for difference in potential in electrical circuits.
VU meters measure the volume (intensity) of analog audio signals. They display signal levels in volume units (VU), a measure of average volume level.
