GF333V2 three phase reference energy meter is a reference standard with the characteristics of wide-range, multifunction and high-precision. It has accuracy class of 0.01 or 0.02. By adopting techniques of DSP, embedded system and automatic temperature balancing and other compensation, it has not only advantages of light weight, small size, high precision, high performance, powerful function, original interface, ease-to-use, but also work stability. It has been designed for universal laboratory and test applications and is intended for checking and the calibration of reference standards for electrical power and energy. In addition, it can be integrated into meter or reference standard test systems of higher accuracy.
This model GF333V2 reference standard can be widely used in fields of electric energy measuring, electric energy laboratories and other relevant industry, not only in laboratories but also at the industrial field.
