The range includes two models: the MIT515 (up to 5 kV) and MIT1015 (up to 10 kV), both supporting insulation resistance, dielectric absorption ratio (DAR), and polarisation index (PI) testing. Megger’s PI Predictor™ reduces PI test duration by up to 50%, boosting productivity when testing multiple phases.
The new innovative patent applied RE>Act test mode allows the user to make accurate measurements by monitoring reabsorption current. This groundbreaking test mode can ensure reabsorption current does not result in incorrectly passing or failing insulation, helping to maintain safety. In addition, the test mode can be used to ensure dangerous return voltages to not occur.
These instruments have no onboard storage and a fixed 3 mA burn/charge current—perfect for environments where advanced features like remote control aren’t required. The high-performance guard terminal ensures measurement accuracy even in high-leakage conditions.
Simple to use, CAT IV 600 V rated, and built for demanding industrial, OEM, and utility applications, the Essential range delivers fast, dependable results—without complexity.
