A data recorder is the ideal addition to an electronic security compliance system. Recorders measure and document many different power quality parameters, including alternating current (AC), AC voltages, harmonics, sags and surges, peak demands, frequency measures, power factors, and active, reactive, and apparent power and energy amounts. Data recorders are high-tech pieces of equipment that are programmable, password protected, and able to record for long periods.
