    Description

    Non Contact Earth Resistance Online Detector Split Core Ground Resistnace Tester
    Instruction:
    ETCR2800KC Split-core Ground Resistnace Detector

    specialize for online monitoring grounding down lead connection status, circuit grounding resistance and metal circuit connection resistance

    range

    0.010Ω~100Ω. 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. 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.
    ETCR2800KC 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.Use by RS485 wire communication or GPRS wireless communication data transmission, realize remote online monitoring
