PITE 5303C-22 Three Phase Standard Meter
PITE 5303C-22 Three Phase standard reference meter, developed by PITE, is a standard electric energy meter with characteristics of wide-range, multifunction and high-precision. It has different option of accuracy class of 0.02, 0.05 and 0.1. 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.
The product 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.
