Megger DET3TD Digital Earth/Ground Resistance Tester
The Megger DET3TD digital ground tester measures earth resistance from 0.01Ω through to 2000Ω and earth voltages up to 100 V. To allow accurate testing in noisy environments the instrument is capable of rejecting noise of up to 40 V peak to peak.
The DET3TD ground tester has been designed to be easy to use - a large selector switch makes selection of 2 and 3 pole tests easy with gloved hands. 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 DET3TD ground tester also automatically checks the connection and condition of the P and 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 ohms through to 2000 ohms and earth voltages up to 100 V. To allow accurate testing in noisy environments the instrument is capable of rejecting noise of up to 40 V peak to peak.
The Megger DET3TD digital ground tester is powered by eight AA batteries which are widely available and also give excellent testing time - the status of these batteries is given by a bar graph on the LCD display allowing you to decide when to change the batteries, before they expire. The Megger DET3TD 3-Terminal Ground Resistance Tester is designed to meet stringent safety standards and is rated CAT IV 100 V.
