The Kewtech KEW4105A is a digital earth resistance tester that is capable of measuring earth resistance across three measurement ranges of 20, 200 and 2000Ω using a 2-wire simplified measurement system.

Also designed not to trip earth leakage circuit breakers when testing and capable of measuring earth voltage, the instrument is incredibly simple to use with rotary dial for choosing the measurement procedure and dedicated test button for activating the test.
