Insulated Resistance Tester

• Insulation resistance tester has various voltage levels of output, large capacity, strong anti-interference, and the instrument uses high-efficiency batteries. Its operation convenience and safety are obviously better than traditional mechanical megger. It is an ideal test instrument for measuring the insulation resistance of large transformers, mutual inductors, generators, high-voltage motors, power capacitors, power cables, lightning arresters and so on.
