MH12 Digital Insulation Resistance Tester

Use the MH12 for compatible insulation-resistance and voltage checks during electrical maintenance.

Check insulation with selectable test voltages

• Selectable test voltages suit different circuits
• Reading storage supports later review
• Automatic discharge assists the test workflow

Technical details

Model: MH12. Test voltages: 50, 100, 250, 500 and 1000 V. Power: eight AA batteries, not included. Includes leads, clip and manual.

Insulation tests apply high voltage. Isolate and discharge the circuit first, verify the instrument's marked limits and follow the manual. This is not a substitute for a dedicated earth-electrode resistance test.
