Megger offers a high-performance ground tester for measuring ground electrode resistance and soil resistivity. The DET2/3 delivers accurate results in the harshest environments.
Ideal for a wide range of applications, ranging from taking accurate measurements on communications ground systems to performing archaeological and geological investigations, this new ground tester is easy to use. If offers excellent error detection capabilities, as well as a large color display that shows detailed test information in both numerical and graphing formats.
Powerful diagnostic tool
The DET2/3 meets IEEE Standard 81 and is suited to testing grounding and lightning protection. It provides ground measurement over a single continuous range from 0.001 Ω to 20 kΩ with a resolution of 1 mΩ. The unit’s test frequencies range from 10 Hz to 200 Hz in steps of 0.5 Hz. An automatic frequency selection feature allows users to ensure tests are carried out at the frequency with the lowest noise level. Test frequency, test current and filtering can also be adjusted manually to optimize results in harsh conditions.
This new ground tester is a powerful diagnostic tool for anyone performing ground testing. Its live display traces are provided during measurements, graphically showing the amount of noise in the ground system under test.
The DET2/3 features a large internal memory that allows immediate calculation of resistivity and can store more than a full day’s worth of test results. These results can be downloaded to a USB flash drive or directly to a PC running PowerDB™ software.
The unit supports two-, three- and four-pole ground resistance measurements, as well as three- and four-pole ART (attached rod technique) measurements and stakeless measurements. Bidirectional continuity and bond testing are supported without the need to reconnect the test leads.
Durable and rugged test equipment
The durable DET2/3 features rugged construction and IP65 ingress protection when closed and IP54 open. It is powered by an internal rapid-recharge Li-ion battery that, when fully charged, will last an entire day under typical testing conditions. The instrument can also be powered from a standard 12 V vehicle supply.
Megger offers an extensive range of optional accessories for the DET2/3, including cable reels with spikes, continuity test cables and clips, as well as a durable water-resistant bag that holds the full range of accessories.
