Professional 2500V Insulation Resistance Tester

A 2500V insulation resistance tester is used by professionals to check the integrity of electrical insulation in high-voltage equipment. It is essential for preventive maintenance and fault finding in motors, heavy-duty cables, transformers, and industrial switchgear, ensuring they are safe from short circuits and leakage currents.

Yes, absolutely. With selectable test voltages from 250V up to 2500V and a massive 200G ohm range, this digital megger meter is perfectly specified for motor winding inspections, cable insulation testing, and transformer maintenance across commercial and industrial settings.

Our auto range megohmmeter measures from 1M ohm (1,000,000 ohms) all the way up to 200G ohms (200,000,000,000 ohms). This wide range allows you to detect both severe faults and subtle degradation in insulation quality over time.

Yes. It functions as an AC DC voltage insulation tester, capable of measuring from 10V to 600V. This is a critical safety feature, allowing you to verify that a circuit is fully de-energised before you begin high-voltage insulation testing.

A standard multimeter typically uses a 9V battery to measure basic resistance, which cannot detect high-voltage insulation breakdowns. An electrical insulation resistance meter generates a high test voltage (up to 2500V) to stress the insulation, revealing faults that a standard multimeter would completely miss.

Yes, it operates as a data storage megohmmeter with the capacity to save up to 100 individual test records. This feature is highly beneficial for UK maintenance engineers needing to log data for compliance reports and historical asset tracking.
