Megger’s DET4 family of ground testing instruments offers a unique solution to your ground rod and soil resistivity testing needs.
The ground tester is rated to IP54 making it truly an outdoor instrument. The DET4TD2 has been designed to be easy to use, a large selector switch makes selection of 2 pole, 3 pole or 4 pole test easy with gloved hands - and the design makes the fitting of shorting links to perform 2 pole tests a thing of the past. A large, clear, easy to read LCD display and thumb sized test button again makes the instrument particularly suited to the outdoor conditions of ground testing.
In addition to this ease of use the ground tester also automatically checks the connection and condition of the P spike and the C spike, indicating the status on the display. The instrument also includes a voltmeter to allow you to measure the ground voltage. The ground tester can measure resistance from 0.01 Ω through to 20 kΩ and earth voltages up to 100 V. To allow testing in noisy environments the instrument is capable of rejecting noise of up to 40 V peak to peak.
The DET4TD2 digital ground tester is powered from 8 AA batteries which are widely available and deliver excellent testing time.
