The DET2/3 high resolution earth tester is a robust and compact automatic ground) test instrument designed to measure earth electrode resistance and soil resistivity. 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 (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.

With its microprocessor controlled system it provides a flexible and user-friendly approach to ground tests by the provision of excellent error detection capabilities and full test information shown on a large colour display. The DET2/3 can provide a live trace of its measurements, which graphically shows the amount of noise from the system under test - a powerful diagnostic tool for the expert earth/ground test engineer.

The DET2/3 also includes an automatic frequency selection feature that scans for frequencies with the lowest noise level and then runs a test at that frequency. The selected test current frequency, test current level, and the increased filtering option are stored in memory for use in subsequent tests.

Use of the latest processors and a large internal memory allows for immediate calculations of resistivity (Wenner or Schlumberger method) and the ability to save a complete days worth of test results. Test result data can be downloaded directly through a USB drive or straight to a Windows PC running PowerDB software.

High Accuracy and Reliable Readings

With an accuracy of 2% of reading plus one digit, the DET 2/3 Ground Tester ensures dependable earth resistance and voltage measurements. The high input impedance design prevents electrode polarization, delivering trustworthy data even in challenging field conditions. The analog display provides high-resolution visuals that make minute changes easily observable during tests.


Safety and Durability

The tester complies with international safety standards, including CAT IV 100V and IEC 61557, and is equipped with short circuit and overload protection. Its robust ABS plastic casing protects against dust and shocks, while the insulation box offers further protection during use. This durable construction makes it suitable for field operations in various environments.


User-Friendly Design and Complete Accessories

Featuring a user-oriented interface, the large analog meter is easy to read. Automatic battery checks and a battery condition indicator add convenience, while low power consumption extends battery life. Supplied with test leads, earth spikes, batteries, and a carrying case, it is prepared for immediate deployment upon delivery.
