Megger DET4TC2 Digital Ground Tester
Includes: Hard carry case, stake and wire kit (15m, 10m, 10m, 3m) and DET4TC2 Calibration Certificate.
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.
