MI-10KVe High-Voltage Insulation Tester

The MI‑10KVe is a portable high-voltage insulation resistance tester, engineered to measure insulation resistances using test voltages up to 10 kV. It delivers reliable, safe readings up to 2,000,000 MΩ (2 TΩ) using four selectable test voltages: 1 kV, 2 kV, 5 kV, and 10 kV.

Its wide analog scale provides real-time feedback ideal for detecting insulation degradation, with a user-friendly display design trusted by field technicians.

Built for use on transmission lines, medium-voltage systems, and cable diagnostics, the MI‑10KVe helps uncover faults and confirm insulation integrity under near-operational voltage conditions.

With a sealed, high-dielectric strength plastic enclosure, the tester is rated IP65 (lid closed), and its rugged, rechargeable design makes it a field-ready solution for demanding environments.
