 Earth Testers 4105A
Earth Testers 4105A
  • Dust and drip proof.(designed to IEC 529 IP54)
  • 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)
  • Designed to meet IEC 61010-1 safety standard.
  • Capable of measuring earth voltage.
  • Automatic warning when resistance of auxiliary earth spikes is in excess of tolerance.
  • 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.
