■ Product Overview
Vs-rxwx wireless multi-channel electrical equipment insulation charged detector is our company on the basis of the original double channel charged detector and developed a more convenient on-site use, more reliable data of a field charged detection instrument, using Beidou satellite timing technology, at the same time equipped with stable and reliable ZigBee wireless communication technology, The instrument completely solves the problems of long-distance cable measurement, data measurement stability and accuracy, and simplifies the field workload. The instrument is far superior to the previous detection system both technically and conveniently.
