- Double clamp / ground piles measurement method: Can be applied to any place to measure whether multi-point or single point grounding.
- Strong anti-interference ability: Self-generating high-frequency current can filter 50Hz and 100Hz harmonic interference current, even in the 500KV substation environment, it can accurately measure.
- Wide measurement range and high resolution: Range from 0.01Ω ~ 200Ω, resolution 0.01Ω, the ground resistance under 0.7Ω also can be accurately measured.
- Large jaw design Jaw diameter is 50mm (standard configuration), which meets the case using flat iron / steel wire grounding, special jaw size can be customized.
- High-capacity data storage It can store 200 sets of measurement datum.
- Simple operation, single-operator Small size, light weight, explosion-proof carrying case, is easy for field measurements.
