Earth Contact Resistance Tester
Direct-Reading ECR Test System, Up to 30 A
Model: PE 900R
Earthing Contact Resistance Testing for Electrical Safety
The PE 900R measures earthing contact resistance in domestic and industrial electrical appliances by passing a high current between accessible metal parts and the earth pin and measuring the resultant voltage drop. Direct resistance indication with internal resistance compensation gives clear, repeatable readings for electrical safety testing.
