Description
Test insulation, continuity, voltage, capacitance and more, then store all the results with this insulation tester from Megger.
The upgraded version of the Megger MIT410, the MIT420’s main benefit is its built-in memory storage. Whenever you’re testing, all results can be stored directly on the tester with easy recall, making this tester ideal for testing over a period of time.
Featuring multiple selectable test voltages (50, 100, 250, 500 and 1000V variable), the Megger MIT420 is suitable for insulation testing up to a maximum of 200GΩ. It’s also possible to use this tester to perform PI (polarisation index) and DAR (dielectric absorption ratio) tests.
This model is the official replacement for the original Megger MIT420. With a redesigned case with built-in backstand for hands-free use, plus new features, this product is ideal for use in both electrical and industrial inspections.
