Description
The Kyoritsu KEW 4105A is a durable Japanese digital earth tester for 3-pole/2-pole ground resistance (0–2000Ω) and earth voltage (0–200V). Low 2mA test current avoids RCD tripping, IP54-rated case, automatic warnings
Soft Case Model
- 3-Pole and 2-Pole Earth Resistance
- The latest circuit design permits the instrument to operate with the minimum of influence from earth voltage and earth resistance of auxiliary earth spikes
- Dust and drip proof (designed to IEC 60529 IP54)
- Designed to meet IEC 61010-1 safety standard
- Capable of measuring earth voltage
- Small and lightweight. Shock resistant new case material
- 2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test
