Megger MIT1025 Insulation Resistance Tester - 10kV, 20 TOhm


The Megger MIT1025 is a 10kV insulation tester with a resistance measurement up to 20 TOhms. The MIT1025 replaces the old MIT1020/2. The MIT1025 is smaller and lighter yet offers advanced features from the previous model. One of these features is the ability to take measurements when connected to line power/mains with a dead battery. Intelligent battery charging ensures the optimum charge rate as a function of battery level, resulting in minimum charge times.

Five preset voltage ranges are provided in insulation test mode, plus a user settable lock voltage range. Any selectable test voltage may be locked and restored via the selector switch, thereby increasing efficiency of commissioning and repetitive tests. Pre-configured diagnostic tests include Polarization Index (PI), Dielectric Absorption Ratio (DAR), Dielectric Discharge (DD), Step Voltage (SV) and Ramp Test.

The rugged, unique dual case design provides the ultimate protection for a portable instrument and a clip-on lead pouch ensures that leads remain with the instrument at all times. Simplicity of operation is achieved with two rotary switches and the large backlit display enables multiple results to be displayed simultaneously.
