GF312B Portable Three Phase Electric Meter Calibration equipment with Printer
GF312B portable three phase energy meter calibrator with printer is used to calibrate three phase, single phase, active and reactive energy meters error. 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 64th harmonic wave. GF312B meter calibrator is used for grid corporation of measurement and energy test center, metrological service of power supply bureau, national energy measurement of testing authorities. It is an ideal testing tool and has been used in more than 80 countries.
