Product Description GF312B portable three phase watt meter
calibrator with printer is used to calibrate three phase, single
phase, active and reactive watt meters. And it also can be used as
voltage, current and power meter to measure AC parameters of three
phase power line.It can measure wave distortion factor and 2nd to
63th harmonic wave. Product Parameters Electrical
