Uses special dual clamps no-connecting method ,do not need subsidiary terrestrial poles, do not need insulate the grounded equipment and load, realizes on-line testing

1. Dual clamp/ ground anchor two methods:
   applies any ground site,  single or multiple point grounding. 
2. Strong anti-jamming ability 
3. Wide measurement range, high resolution 
   range: 0.01Ω~200Ω, resolution: 0.01Ω, 
4. Big jaw design:
   diameter :50mm (standard), special size according customers’ requirements. 
5. Large-capacity data storage:200 groups
6. Easy to operate:
   small in volume, light in weight, portable explosion proof case, convenient to field test to carry.
