These insulation resistance testers can be battery or mains powered and feature an on-board memory for storing results. The digital or analogue backlit display is large, making it easy to read and suitable for use in bright sunlight and application with poor light.
The intuitive controls are easy to use, and a "quick start" guide is located under the lid, making it unnecessary to carry bulky manuals on site.
For enhanced accuracy, MIT520 and 1020 insulation resistance testers are fitted with a guard terminal. The guard test lead is included as standard with the instrument.
MIT520 and 1020 insulation resistance test instruments have been specifically designed to meet high safety standards and they are also compliant to the requirements of EN61010.
