LISUN High-Voltage Insulation Resistance Tester

The LS-IR1515Y High-Voltage Insulation Resistance Tester (high-voltage megohmmeter) offers comprehensive insulation testing functions, a user-defined test voltage function, and strong anti-interference capability for strong-induction environments such as substations and applications with large distributed capacitance.

A 5-inch true-colour touchscreen displays all test data and battery status. Measurement indicators include Insulation Resistance (IR), Polarization Index (PI), Dielectric Absorption Ratio (DAR), Step Test, Ramp Test, Dielectric Discharge (DD), Distributed Capacitance and AC/DC Voltage. A voltage monitor automatically detects live voltage on the test object and blocks testing above 36V for operator safety. Test data (1000 records) stores automatically with date and time stamps, with USB and Bluetooth upload to PC or phone. IP65 rated (cover closed) double-layer casing; large-capacity rechargeable lithium battery (14.8V 6400mAh) for extended field use.

Rated voltages: 50V, 250V, 500V, 1kV, 2.5kV, 5kV, 10kV, 15kV. Insulation resistance range: 0.005 to 30.0 TOhm. Max short-circuit current: 7mA. Capacitance range: 10nF to 200uF. Display: 5-inch TFT touchscreen. Power: 14.8V 6400mAh Li-ion. Protection: IP65 (closed). Weight: approx 5.7kg incl. accessories.
