TW-10C Earth Tester
TW-10C Earth Tester is latest digital precision earth resistance tester of our company, it is with these functions below:
Features:
 1. When measuring by 2-pole, there is no need digging the auxiliary rod, the test is simple and fast.
2. It could measure earth resistance and soil resistivity by 3-pole and 4-pole; also it could measure AC voltage.
3. It should display noise during test and signal when a battery is replaced
4. It should display signal when it exceeds the test range.
5. The instrument would automatically stop the measurement when performing misoperation,
6. International standard: ISO9001:2000
