Leakage marking test is to apply a set voltage on the surface of a solid insulating material, between two electrodes, and drop a specified concentration of liquid at a certain height to evaluate the leakage marking resistance of the surface of a solid insulating material under electric field and contaminated media.
Suitable for lighting equipment, low voltage electrical appliances, room electrical appliances, machine tools electrical appliances, used in insulation materials, engineering plastics, electrical connectors.

1, drop accurate: the use of precision plunger pump as the contaminated liquid supply system, the flow rate is uniform and stable;
2, test voltage stability: high sampling frequency, accurate measurement value, control system with automatic voltage regulation function, not affected by power grid voltage fluctuations, large equipment capacity, low voltage drop under test conditions;
3, high test efficiency: 5 tests can be carried out at the same time, each road is relatively independent, high efficiency, strong comparability;
4, safe and reliable: the system has an exhaust system, timely elimination of harmful gases generated by discharge, and has self-locking, door interlocking, zero limit start, upper limit protection, overcurrent, overvoltage and other protection functions.
