DET3TC
DET3TC Digital Three Pole Earth Testing Kit with ART

The ground rod tester is rated to IP54 meaking it truly an outdoor instrument. The ground tester has been designed to be easy to use - a large selector switch makes selection of 2 pole or 3 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.

Using the optional clamp around the ground rod connection allows the testing of the rod without the need for disconnection, leaving the earthing system intact during testing (ART). 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 of the P spike 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.


DET3TD
DET3TD Digital Three Pole Earth Testing Kit
The Megger 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 ground testers are designed to meet stringent safety standards and are rated CAT IV 100 V.

DET4TC2
DET4TC2 Earth/Ground Resistance Tester (Battery)

The DET4TC2 includes a current measuring function for ART (Attached Rod Technique) testing capabilities. With this added function, on-site grounds can be tested separately without having to remove the utility connection.

The new DET4TC2 and DET4TCR2 also provide a stakeless testing technique. It allows the operator to use the instrument like a clamp-on ground tester in applications where that method is viable, while also being able to operate as a fall of potential tester.

The complete kit of instrument, test leads, stakes, batteries and calibration certificate are delivered in a tough polypropylene carry case – everything you need to start testing in one package. Optional terminal adapters are available for acceptance of a variety of test leads.
