MEGGER DET4 Series | FOUR-TERMINAL DIGITAL EARTH/GROUND TESTERS

MEGGER DET4 Series | FOUR-TERMINAL DIGITAL EARTH/GROUND TESTERS

Megger’s popular 4-terminal ground testing instrument family includes four basic models with different kit variants for each that include select accessories for greater testing flexibility. All models are rated to IP54, making them truly outdoor instruments. They are designed to meet stringent safety standards and are rated CAT IV 100 V. The ground testers have been designed to be easy to use – a large selector switch makes selection of 2, 3 or 4 pole tests easy with gloved hands – and the design makes the fitting of shorting links to perform 2-pole tests a thing of the past.
