The Megger MIT2500 (1004-745) Insulation and Continuity Tester has been designed for motor and cable testing, specialist applications and electrical testing applications, where operation voltages exceed 1000 V and higher insulation test voltages are needed.

The MIT2500 offers both fixed range voltages of 50 V, 100V, 250 V, 500 V, 1000 V and 2500 V, as well as a variable range that allows any voltage between 50 V and 2500 V to be "dialed in". This is supported by the test voltage feedback control, which maintains the output test voltage to within 2% of the selected range, even when under testing.

The MIT2500 uses a redesigned case, back-stand, and 6-cell battery compartment. The tester furthermore has an incorporated guard terminal to reduce surface tracking currents that reduce accuracy at higher voltages. The MIT2500 is over-molded for increased protection and to achieve an IP54 weatherproof rating.
