Megger MIT2500 Insulation Tester
Megger MIT2500 Insulation Tester
The MIT2500 high voltage handheld insulation and continuity tester is designed for motor and cable testing, specialist applications, and electrical testing scenarios where operating voltages exceed 1000 V and higher insulation test voltages are required.
The Megger MIT2500 offers both fixed voltage ranges of 50 V, 100 V, 250 V, 500 V, 1000 V, and 2500 V, and a variable range that allows you to dial in any voltage between 50 V and 2500 V. This is supported by new test voltage feedback control, which maintains the output test voltage within 2% of the selected range, even during testing.
The feedback-controlled insulation test voltage is now accurate to +2% -0%, compared to the original +20%, providing a more precise test voltage without the risk of overvoltage damage to circuits. The variable range allows the exact test voltage to be selected from 50 V to 999 V in 1 V increments, and from 1 kV to 2.5 kV in 10 V increments, offering 1100 test voltage options.
