Megger MIT2500 Insulation Tester – 0.01 Ω to 1.0 MΩ resistance range

Megger MIT2500 Insulation Tester – High-Voltage 2.5kV Insulation Resistance Testing

The Megger MIT2500 Insulation Tester is a powerful, handheld high-voltage insulation resistance tester designed for applications that require more than 1000V test capability. With selectable test voltages up to 2500V, this instrument is ideal for industrial electrical maintenance, high-voltage equipment testing, and advanced insulation diagnostics in demanding environments.

Built for electrical engineers, technicians, and maintenance professionals, the Megger MIT2500 combines precision, durability, and smart test automation to ensure accurate and repeatable readings every time.

Advanced High-Voltage Insulation Testing (Up to 2500V)

If you need an insulation tester that goes beyond the limits of standard 1000V models, the MIT2500 delivers exceptional flexibility. It offers six fixed test ranges:

• 50V

• 100V

• 250V

• 500V

• 1000V

• 2500V

For applications requiring specific voltage adjustments, the MIT2500 includes a variable test voltage range from 50V to 2500V, allowing engineers to fine-tune test conditions based on equipment requirements. This makes it ideal for electrical panels, motors, generators, cables, and high-voltage installations.

Test Voltage Feedback Control for Superior Accuracy

One of the standout features of the Megger MIT2500 is its test voltage feedback control system, which keeps the output voltage within ±2% of the selected test level, even under load.

This ensures accurate insulation resistance readings, especially when testing long cables, capacitive loads, or large electrical equipment.

To enhance usability, the tester includes:

• A small digital readout showing the actual output test voltage

• A large primary display for insulation resistance measurements

This dual display setup improves clarity, safety, and confidence while testing.

Enhanced Continuity & Resistance Testing Performance

The MIT2500 insulation tester is more than a high-voltage IR meter — it also provides advanced continuity testing capabilities. Key functions include:

• Differential continuity measurement between two consecutive tests

• A full 0.01 Ω to 1.0 MΩ resistance range

• Automatic bi-directional continuity testing, eliminating the need to reconnect test leads

These features make troubleshooting faster and more efficient, especially in industrial maintenance and commissioning work.
