Megger DET3 [DET3TC] 3-Terminal Ground Resistance Tester with Attached Rod Technique Testing

The Megger DET3TC 3-Terminal Ground Resistance Tester is rated to IP54, making it a truly outdoor instrument. It is designed to meet stringent safety standards and is rated CAT IV 100V. The DET3TC Ground Tester is easy to use - a large selector switch makes selection of 2 or 3 pole tests easy with gloved hands.. A large, clear, easy to read LCD display and thumb-sized test button also makes the instrument particularly well-suited to the outdoor conditions of ground testing. In addition to this ease of use feature, the ground tester automatically checks the connection and conditions of the P spike, C spike, and also the level of ground noise, indicating the status on the display. The DET3TC also includes a voltmeter to enable measurement of ground voltage. It can measure resistance from 0.01 ohms to 2 kiloohms. Also, to allow accurate testing in noisy environments, the DET3TC is capable of rejecting noise up to 40V peak to peak.

The Megger DET3TC 3-Terminal Ground Resistance 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 the operator to decide when to change the batteries before they expire.

By using the optional ICLAMP with the DET3TC, users can augment the traditional fall-of-potential measurement method with ART (Attached Rod Technique), which allows electrode testing without disconnection and also leakage current measurements down to 0.5 mA.
