WN6800 double-clamp multi-function grounding resistance tester for telecommunications, electricity, weather, room, power distribution lines, tower transmission lines, gas stations, factory grounding network, lightning rods and so on.

The instrument in addition to traditional auxiliary ground to measure the resistance of the function, but also has a non-auxiliary ground measurement of the unique features to change the test grounding resistance of the traditional measurement principles and means: It can realize the on-line measurement, and it can be measured by the auxiliary pole grounding method under the condition of single-point grounding system and strong interference, and so on.
Grounding system is the important guarantee for the safe and reliable operation of electric power, telecommunication and electrical equipment.Grounding resistance is the basis of the quality of grounding system.It is an accurate, fast, simple and reliable grounding resistance measurement method, Within the urgent need for technological progress.

'main feature'
1, double-clamp method / double-pile method of measurement:
Suitable for any grounded sites, multi-point or single-point ground, can be normal testing;
2, anti-interference ability:
Since the generation of high-frequency current, so as to filter the mains 50Hz, 100Hz and other harmonic interference current, even in the 500KV substation environment, but also accurate measurement;
3, a wide range of measurement, high resolution:
Range from 0.01Ω ~ 200Ω, resolution 0.01Ω, 0.7Ω following grounding resistance, but also accurate measurement;
4, large jaw design:
Jaw diameter 50mm (standard configuration), to meet the flat iron / steel for the ground lead, the special size can be customized according to customer requirements;
5, high-capacity data storage:
Can store 200 sets of measurement data;
6, simple operation, single homework:
All Chinese user interface, small size, light weight, explosion-proof portable case, field measurements to facilitate easy to carry.
