Megger DET4 Ground Tester the comprehensive solution to your ground stake / soil resistivity testing needs
Megger DET4 provides all the functions required for ground system testing:
- Variable frequency 2 pole
- 3 pole
- 4 pole
- Attached Rod Technique (ART)
- Stakeless measurements
- Leakage current
- Ground noise voltage measurement
Unlike some instruments, the DET4‘s design negates the need for a shorting link when making two pole measurements.
The optional MCC CLAMP augments the traditional fall-of-potential measurement method with ART (Attached Rod Technique) which allows electrode testing without disconnection and also leakage current measurements down to 1 mA. A second optional clamp, the MVC CLAMP, enables true stakeless measurements to be made in situations where driving stakes is not practical.
Megger DET4 offers a wide measurement range of 0.01 Ω a to 200 kΩ, ground noise voltage measurement from 1 V to 100 V and ground current from 1 mA to 20 A. Accurate results can be obtained in electrically noisy environments since the instrument is capable of rejecting noise voltages of 40 V peak to peak and the user can select different test frequencies to minimise the effect of interference.
The Megger ground testers comply with stringent safety standards and are rated to 100 V CAT IV. They also have selectable 25 V or 50 V output for compliance with IEC 61557-5.
