Feature:1. Stable and Reliable: The built in sensor and circuit board of the detector are completely closed to ensure high accuracy, stability and reliability of long term online monitoring in the field or indoor2. Non Contact Measurement: This detector conducts non contact online measurement through the ground wire, which does not affect the protection grounding effect and the normal operation of the facility3. GPRS Communication: This grounding resistance online detector adopts GPRS wireless communication to transmit data to realize remote online monitoring4. Function: This earthing ground tester can detect in real time, has sound and light alarm, and automatically shifts gears5. Usage: This monitor is suitable for grounding of transmission line towers, meteorological protection, petrochemicals, communications, substations, railway facilities, building warehouses, electrical equipment, etc.Specification:Item Type: Grounding Resistance Online DetectorMaterial: PVCModel: ETCR2800KBUsage: Suitable for grounding of transmission line towers, meteorological protection, petrochemicals, communications, substations, railway facilities, building warehouses, electrical equipment, etc.Basic Parameters:Function: Loop grounding resistance online monitoring, metal loop connection resistance online monitoring, grounding condition monitoringCT Structure: Open and closeResistance Range: 0.01Ω-100ΩResolution: 0.001ΩAccuracy: ±2%rdg±3dgt (20℃±5℃, below 70%RH)Overflow Indication: When the test value is greater than 100Ω, the LCD displays OLΩAlarm Indication: Sound and light alarmAlarm Settings: Panel button settings, background settingsWorking Temperature and Humidity: -20℃ to 55℃; 20%RH-90%RHTemperature and Humidity Error: No more than 5%Shifting: Automatic shiftingExternal Magnetic Field: External Electric Field: Single Measurement Time: About 0.5 secondsPower
