HIGH PRECISION ONSITE PORTABLE THREE PHASE REFERENCE METER

GF312V2S portable three phase reference meter on-site is the newest product produced by our company by widely visiting users and referring to the advantages of the same kind of products home and abroad. The measured part of the product adopts high speed 24bit A/D transmission to send DSP to conduct digital processing, unique power compensation algorithm with patented technology, which largely improves measured degree of accuracy and stability. Central processing part adopts 32-bit ARM embedded technology to make instrument interface novel, function abundant, operation distinct and easy, and performance steady. Class of accuracy: Class 0.02 or 0.05, range from 3×12A/3×600V or 3×120A/3×600V, with comfort portable design and light weight. The model GF312V2S portable reference meter is suit for electricity power utilities metrogical departments, Industrial and mining enterprises departments and electric lab to field use.
