GF112W Laboratory High Precision Digital Watt Meter

Laboratory digital watt meter

GF112W made in GFUVE GROUP, is a single phase high precision digital watt meter in class 0.05, 0.1, used for testing all kinds of single phase power system. Wide measurement range from 1mA to 10A or 20A and 0 to 600V, frequency range 40.000Hz to 70.000Hz, and also can be used to test alternating current electrical parameters - voltage, current, active power, reactive power, apparent power, harmonics, phase angle, power factor, frequency, kWh etc. It can display U & I wave form and vector diagram. Small size design, light weight, simple and convenient operation. It is an ideal high precision watt meter for the electrical laboratory and onsite service engineers.
