| Tester of the resistance of ground 3143 |
|
 Compact, convenient, portable instrument for measuring the ground resistance to 500 Ohm
- The possibility to conduct the measurements of the ground resistance even in those places, where the earth has a coating (for example, asphalt or concrete, without disrupting its integrity)
- There is no need of using of auxiliary pintles, measurement they are produced without them
