GF111 single phase reference standard meter for test bench
GF111 reference meter is a single phase reference standard with the characteristics of wide-range 600V/240A, multifunction and high-precision. It has accuracy class of 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 can measure U, I, P, Q, S, E, frequency, power factor, phase angle, harmonics etc.
The GF111 energy reference meter 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. It can as a reference standard for single phase energy meter test bench.
