Suitable for both two and three wire testing procedures, the Megger DET3TD is capable of measuring earth resistance from 0.01 to 2000Ω.

Designed for use in a wide variety of environments (including when wearing gloves thanks to large-size rotary dial and testing buttons) the Megger DET3TD automatically checks the connection and condition of P and C spikes with direct indication on the display. A built-in voltmeter also allows the user to measure ground voltage values between 0 to 100V AC.

Megger's earth testers have integrated noise rejection from 40V peak to peak, ensuring that the effects of high levels of electrical noise don't compromise testing results. This allows the DET3TD to be used in even the noisiest of electrical environments and ensures you have one tester for every application.

The Megger DET3TD is rated to CAT IV 100V.
