The Megger MIT2500 insulation tester is designed for electrical and industrial test applications where operation voltages exceed 1000V and higher insulation test voltages are needed. Offering both fixed and variable ranges to 2500V, is ideal for motor and cable testing, specialist applications and a wide variety of commercial and industrial electrical testing applications.

The MIT2500 offers both fixed range voltages of 50, 100, 250, 500, 1000 and 2500V, as well as a variable range that allows any voltage between 50 and 2500V to be set. The instrument maintains ±2% accuracy by a feedback control feature which maintains the output test voltage to within 2% of the selected range, even when under test. Additionally, a guard terminal provides a return path for parallel leakage currents that could otherwise create significant errors in the insulation measurement.

The MIT2500 includes a dual digital display which indiates both the actual test voltage and the measurement voltage as well as an analog arc to replicate the response of a moving coil display. The instrument is designed to be used anywhere and includes strong modified ABS housing with rubber over-moulded to create an almost indestructible case. The MIT2500 is sealed to IP54 providing a weatherproof case to reduce the chances of water ingress, including the battery and fuse compartment.
