Kyoritsu 4105A Earth Tester
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 standard.
Capable of measuring earth voltage.
Small and light weight. Shock resistant new case material.
2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test.
