C.A. 6421 Analogue Earth Tester

The C.A. 6421 Analogue Earth Tester is a stand-alone and reliable earth tester with a measurement range up to 1000Ω. The CA 6421 offers both 2-pole and 3-pole methods of testing. The 6421 analogue earth tester also has a removable captive connection strip between S and H terminals for 2-wire resistance measurements. This self-contained, leakproof and lightweight earth tester is perfectly suited to use in the field. Earth resistance is measured on a large, rugged galvanometer using traditional rod methods. The C.A. 6421 is the ideal earth tester for those who prefer an analogue instrument.
