Digital Earth ResistanceTester

Digital Earth ResistanceTester 1. ISO9001:2000 2. UL

Digital Earth Resistance Tester

1 Features:

Earth resistance clamp is a breakthrough from traditional tester. Neither the supplementary earth leads nor the break earth equipment is necessary. Ground resistance result can be get safe and fast only by clamping the ground line.It is also widely used in the field of electric power distribution, telecommunication and architectural ground.

· Two pole and three pole AC resistance test and DC resistance test

· Three pole and four pole earth resistance test

· Four pole test the ground resistivity directly

· With current-clamp selection you should not cut the earth connection

· Optional test voltage 20V/48V

· Automatic frequency control(AFC),can auto distinguish interference and choose the suitable test frequency, minimize the influence of interference.94Hz,128Hz optional.

· With test data storage function, can store 100 test data, upload to the PC and analysis, output the test report

· Alarm function

· Clock function

· Two power supply-dry battery or rechargeable battery
