3-Phase Precision Power Meter offers accurate measurements of active power, trms value, mean value and peak value of voltage and current. The Precision Power Meter is used for testing single phase and three phase AC machines. The Precision Power Meter is micro-controller based instrument and compact in design. The 3-Phase Precision Power Meter can measure current directly from 80mA to 80A and voltage directly from 6V to 600V.
