Description Specification Ordering instruction

PMC72S is a true RMS-based measuring meter that can accurately measure highly nonlinear loads. Its advanced grid frequency synchronization sampling technology enables it to accurately measure a variety of power parameters, including voltage/current RMS, frequency, active power, reactive power, apparent power, power factor, input/output active energy, total active energy, Input/output reactive power, total reactive power, apparent power, voltage total harmonic distortion (THD), 1~31 voltage harmonics, current total harmonic distortion (THD) and 1~31 current harmonics, etc. . All measurement values, min value and max value, and demand measurement values can be viewed on the screen display or be checked via remotely software control.
