Energy meters measure the total energy of a single pulse and optical power meters measure the average power of a continuous light beam

DC power supplies accept an input power and output the desired form of DC power.

Power meters are used for high-accuracy measurements of power over a wide-frequency bandwidth, and from both AC and DC circuits

Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement).

High voltage power supplies use linear technology to provide one or more DC outputs at voltage levels of hundreds or thousands of volts

Calibration instruments use electrical signals or physical quantities to calibrate sensors and meters.

Battery and fuel cell test equipment consists of specialized test stations, stands or systems, monitors and component modules for performance or endurance testing.
