Non-Contact Grounding Resistance Online Detector Earth Resistance Tester Meter

Note: Battery cannot be included during the shipping !!!

Introduction:

1. Non-Contact Grounding resistance Online Detector used for on-line monitoring the earthing resistance of earthing system, measure range: 0.010 Ω ~200 Ω . 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.

2. 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.
