Power quality analyzers measure and monitor electrical power parameters to avoid disturbances, track steady-state variations, and ensure the reliability of power distribution systems

Spectrum analyzers and signal analyzers display raw, unprocessed signal information such as voltage, power, period, wave shape, sidebands, and frequency.

Gas and air instruments detect, monitor or analyze gases present in an environment.

Particle size, shape and count analyzers are used to determine the physical makeup of individual particulates in aerosols, dispersion, emulsions, powders and other sample types

Optical spectrum analyzers (OSA) can divide a lightwave signal into its constituent wavelengths.

Laser beam analyzers are used to determine the quality of a laser beam

KVA meters measure the apparent power of AC devices in kilovolt-amperes (KVA).
