DET2/3

HIGH RESOLUTION EARTH TESTER

The DET2/3 is a robust and compact automatic earth (ground) test instrument designed to measure earth electrode resistance and soil resistivity. The DET includes the option for remote control. For use on large or more complex earth systems, which include communications earth systems and difficult test environments, it can be used to test in accordance with BS 7430 (earthing / grounding), BS-EN-62305 (Lightning Protection), BS-EN-50122-1 (Railway Applications), and IEEE Standard 81.

Test frequency, test current and filtering can be quickly and easily adjusted so that adverse conditions, which can influence the test, can be overcome, and a wide band of test current frequencies, with a resolution of 0.5 Hz, can be used to eliminate errors caused by noise in the earth.

DET14C and DET24C

Digital Earth Clamps

  • Elliptical clamp shape improves access to earth cables and straps up to 50 mm
  •  Low maintenance flat jaw interface
  •  Measures ground resistance from 0.05 Ω to 1500 Ω
  •  Measures true RMS ground leakage current from 0.5 mA rms to 35 A rms
  •  CAT IV 600 V safety rating
  •  Backlit LCD display

The DET14C and DET24C represent a new generation of earth/ground clamp-on resistance testers. These instruments induce a test current into earth systems and measure ground resistance in multi ground installations without needing to disconnect the ground. They offer market leading access, advanced features, simple operation and CAT IV 600 V safety protection.

The elliptical shaped head design offers improved access to cables and earth straps in space constrained locations. The clamp head accommodates up to 37 mm diameter cable and 50 mm earth tapes making them suitable for use in power stations, substations, towers and many more facilities.
