AL604 Clamp Ground Resistance Tester
Performance standards:
DL/T845.2-2004
Features:
1, applies to various forms of ground wire (garden steel, flat steel and angle iron).
2, non-contact measurement of ground resistance, safe, fast.
3, without the use of auxiliary ground rods, the device under test is not required to break the ground.
4, has a dual protective insulation.
5, strong anti-interference, measurement accuracy.
6, the use of alkaline batteries, 5 user.
