Megger MIT525 Insulation Resistance Tester Description

The Megger MIT525 insulation resistance tester is a great tool for identifying the efficacy of the electrical insulation of a product. The device is highly safe to use because it comes with double-insulated leads in a tough, fire proof carry case. It also comes with five preset voltage ranges, which assist user interface. We offer the MIT525 to rent for as little as £90 per week.
