Megger DET4TC2 Digital Ground Tester

The Megger DET4TC2 is designed for extended temperature range use with an IP54 rated enclosure making it a genuinely outdoor instrument. The instrument provides all the functions required for ground system testing: variable frequency 2 pole, 3 pole, 4 pole, Attached Rod Technique (ART), stakeless, leakage current and ground noise voltage measurement. The instrument is easy to use with a large rotary selector switch and one-press test button, both of which permit operation with gloved hands. Unlike some instruments, the design negates the need for a shorting link when making two pole measurements. FEATURES IP54 rated. 2, 3 and 4 point testing. Attached Rod Technique (ART).
