Kyoritsu KEW 4105A Earth Resistance Tester CAT III 300V with Soft Case

The Kyoritsu KEW 4105A Earth Resistance Tester is a compact and lightweight testing instrument designed for reliable earth resistance measurement in electrical installation, maintenance and inspection work.

It supports both 3-pole and 2-pole earth resistance testing and can also measure earth voltage up to 200V AC. The instrument uses a 2mA measuring current, helping to carry out earth resistance testing without tripping earth leakage current breakers in the circuit under test.

The KEW 4105A features a large, easy-to-read LCD digital display, a shock-resistant body, and a dust and drip proof design to IEC 60529 IP54, making it suitable for practical field use.
