The ERT 1557 is a high specification ground bond tester.

Suitable for use on 110 v, 230 v and three phase electrical systems, this special lightweight unit provides accurate earth electrode resistance measurement without disconnecting the electrode. It can also be used to measure soil resistivity.

Ground bond resistance measurement is carried out using 2, 3 and 4-wire method. The ERT has an internal memory for 500 test results which you can download to your conventional PC. Its user-friendly features include a large rotary dial for test selection, large LCD and simple push button test activation. The unit is supplied with four Earth spikes and full test lead set. The ERT is one of the most competitive Ground resistance testers on the market.
