Megger DET4TR2- 4-TERMINAL GROUND RESISTANCE AND SOIL RESISTIVITY TESTER

A fully rechargeable version of Megger’s DET4TD2 earth tester, the DET4TR2 is an ideal solution for those looking for a high accuracy earth testing instrument that won’t constantly require you to replace the batteries.

This earth tester is capable of carrying out 2, 3 and 4 wire testing with no shorting links required, allowing resistance to be measured from 0.01Ω to 20kΩ with a high degree of accuracy (2%±3 digits). The tester can also be used to calculate earth voltage levels from 0-100V with accuracy of 2% ± 2V. In addition to these standard measurements the DET4TR2 also includes the ability to automatically check the connection and condition of connected P and C spikes, with both values displayed on the tester’s built-in LCD screen.

Accuracy when testing with this instrument is also guaranteed due to a built-in noise filter that detects and filters out the effects of electrical noise of up to 40V peak to peak.

The DET4TR2 is built to last – it’s encased with a heavy duty casing to protect the tester from harm and also comes with IP54 protection against dust and water damage, making this tester suitable for use both indoors and outdoors.
