The CA 6421 Analogue Earth Tester is an independent, dependable earth tester with a measuring range up to 1000. The CA 6421 provides both 2-pole and 3-pole testing options. In addition, the S and H terminals of the 6421 analogue earth tester have a detachable captive connection strip for measuring 2-wire resistance. This earth tester is ideal for use in the field because it is self-contained, leakproof, and light weight. Traditional rod methods are used to test earth resistance using a big, tough galvanometer. For those who prefer an analogue instrument, the Chauvin Arnoux CA 6421 is the perfect earth tester.
