ETCR2200 High-end Multifunction Clamp Earth Resistance Tester

ETCR2200 High-end Multifunction Clamp Earth Resistance Tester

Product Main Function

1. Measurement of earth resistance,loop resistance

2. Resistance Measure Range: 0.010Ω~1500Ω

3. Leakage Current Measure Range: 0.000mA~40.0A

4. Alarm Threshold Setting:Resistance: 1-199Ω ; Current: 1-499mA

5. Alarm Function: audible and visible alarm

    ETCR2200 High-end Multifunction Clamp Earth Resistance Tester is applied in measurement of  grounding resistance and the loop resistance (range: 0.010 Ω Ω ~ 1500); Leakage current measurement (Range: 0.000mA~40.0A). When measuring the earth system with loop, there is no need to disconnect the grounding down lead, no need for auxiliary electrode, just need to clamp  on the grounding lead directly. At this time, the displayed value of the meter  is the comprehensive value of the grounding resistance and the grounding down lead resistance. This measurement method can quickly and safely to get the measurement results. 

      ETCR Clamp Earth Resistance Tester can measure the ground fault and applied to the occasions that cannot be measured by traditional methods, and it is widely used for the earth resistance measurement of various equipment.

     ETCR2200 High-end Multifunction Clamp Earth Resistance Tester has different kinds of display combination mode,can choose to display at same screen with resistance + current, resistance+time, current+time,measurement range more larger,storage data 999 sets,power consumption more lower,adopt nickel-metal hydride rechargeable battery, supporting monitoring software with online real-time monitoring, historical query, software alarm setting, historical data reading, saving, reports and other functions. The better choice for your measurement of earth resistance.
