Non Contact Grounding Resistance Online Detector Earth Resistance Tester 200Ω

Description: Non Contact Grounding Resistance Detector Online Earth Resistance Tester 200Ω Instruction:Non-Contact Grounding resistance Online Detector used for on-line monitoring the earthing resistance of earthing system, measure range: 0.010Ω~200Ω. On-line testing, non-contact measurement, grounding wire pass through the perforation of the detector, definitely not influence grounding for lightening effect and normal operation, real time on-line testing. Use by RS485 wire communication or GPRS wireless communication data transmission, realize remote online monitoring .Detector built-in sensor and circuit board, completely sealed, ensure high-accuracy, high stability and high reliability of long time on-line monitoring at field and indoors. Non-contact Earth Resistance Online Detector, can display the measured data directly through the LCD; the detector could set alarm threshold, with sound and light alarm indication, suitable for independent installation and use no need to set up the network. Product Main Function1.On- line monitoring the earth resistance of grounding system 2. Measure Range: 0.010Ω~200Ω 3. With GPRS communication and RS485 interface 4. 47mm×28.5mm LCD 5.
