ETCR3000 DigitalEarthResistance Tester isspeciallydesigned
and manufactured forfieldmeasurement, adoptingthelatest digital
and micro-processingtechnology,3-poleor2-polemethod for
earthresistancemeasurement, withaunique function ofwire
resistanceverification, anti-interferencecapabilityandtheabilityto
adapttothe environment, toensurehighprecision,highstability
and reliabilityforprolonged measure,whichiswidelyusedin
electricpower,telecommunications,meteorology,oil field,
construction,lightningprotection,industrialelectricalequipment
and otherearthground resistancemeasurement.
ETCR3000 DigitalEarthResistance Tester hasaunique
function ofwireresistanceverification ，moreaccurateon
