Product Overview

The 382252 from Extech Instruments is a earth ground resistance tester kit. This kit includes all hardware necessary to measure earth ground in 3 ranges from 20 ohm to 2000 ohm. It also tests AC/DC voltage, resistance and continuity. The tester features automatic zero adjustment and three earth ground resistance ranges 20 ohm/200 ohm/2000 ohm. It has 20 ohm/200 ohm/ 2000 ohm earth ground resistance (0.01 ohm/0.1ohm/1ohm resolution, ±(2% reading + 10 digits) accuracy). This device is designed to meet EN61010-1 safety standards. Careful care and use of this meter will provide years of reliable service.
