Split-core Ground Resistnace Detector Earth Resistance Tester Meter 0.01Ω~100Ω

Description: Split-core Ground Resistnace Detector Earth Resistance Tester Meter 0.01Ω~100Ω Note: Battery cannot be included during the shipping !!! Introduction: 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. 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. Function:On - line monitoring the earth resistance of grounding systemMeasure Range: 0.010Ω~100ΩNo need to disconnect the grounding down lead and no need with auxiliary electrodesRain and dust proof, can be installed and used in outdoorNetwork system can be built to realize real-time detection and remote monitoringEX-Mark: ExiaⅡBT3GaExplosion Proof Certification: CE18.2332X Specifications: FunctionReturn circuit grounding resistance on-line monitoring, metal return circuit resistance connection online monitoring, grounding condition monitoring.
