Product Characteristics
1, the insulation test of the instrument for KG312 can measure up to 20GΩ at 500V, up to 40GΩ at 1000V, up to 100GΩ at 2500V.
2, the rated output voltage is maintained at the KG312 type load resistance can be as low as 4MΩ/8MΩ/20MΩ; For KG3122, 20MΩ/40MΩ; For the KG3123 model 40MΩ/80MΩ, this allows the meter to accurately measure the lower insulation impedance.
3, automatic conversion of high-low range dual-scale indicator, color scale is easy to read, and LED display the corresponding color.
4, the whole machine adopts ABS plastic case portable design, with strong anti-interference ability, compact structure, beautiful appearance.
5, the instrument adopts ultra-thin wire watch head, strong seismic ability.
6, AC and DC dual use, built-in rechargeable battery and intelligent charging module.
7, it is an ideal test instrument for measuring insulation resistance of transformers, transformers, generators, high-voltage motors, power capacitors, power cables, arresters, etc.
