KEW 4105A Earth Tester Kyoritsu

• In addition to the facility for precision measurement, test leads for simplified two wire measuring system also supplied as standard accessories.
(unit can be hung from the neck for simplified measurement)
• 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)
• Earth resistance value can be read directly from the scale.
• Designed to meet IEC 61010-1 safety standards.
• 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.
