Introduction:

1. Applicable for grounding resistance and circuit resistance measurement in mining, industrial park, electricity, telecom, meteorological, oilfield, architecture and  industrial motor equipment fields.

2. It can do measurement directly and no need to disconnect grounding wire or prepare auxiliary electrode.

3. Applicable for the combustible and explosive gas place.

4. Measured value is the comprehensive value of grounding body resistance and grounding wire resistance.

 

Technology parameters:

1. Measuring range, resolution and intrinsic error.
