Electrical 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

Current transformers are used to step down current in a very predictable fashion with respect to current and phase. They are generally used as inputs to current instruments

Current leakage testers measure the amount of current that leaks to ground

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

Conductivity meters, dissolved solids meters, and resistivity meters are analytical instruments that measure the conductivity, dissolved solids, and/or resistivity of a liquid sample

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

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

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

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

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

Non-destructive testing (NDT) conductivity meters and resistivity meters are devices for measuring electrical conductivity and/or resistivity of solid media to determine the characteristics of its constituent materials

Instrument transformers are used to step-down current or voltage to measurable values. They provide standardized, useable levels of current or voltage in a variety of power monitoring and measurement applications

Milliohm meters are capable of measuring very small resistances

EMF meters detect and monitor harmful electric, magnetic or electromagnetic fields surrounding personal or work areas
