Product Description
Description:ETCR2900 Online Earth Resistance Tester composed of the detector and the monitoring software. The large LCD display of the detector is very intuitive. Setting the alarm thresholds and audible and visible alarm indicator are available. The material of the shell has the characteristic of resistance to high low temperature, corrosion prevention, inflaming retarding etc, ensure high-accuracy, high stability and high reliability of long time on-line monitoring outdoors, underground mine and indoors. The monitor software can real-time display the values of measured ground resistance and voltage. The user also can set the automatic monitoring interval time by the detector or the monitor software, the range of interval time is 1-999 hours. The automatic recording data can be generated reports, it is convenient to preservation, historical data query, print, analysis.
ETCR2900 Online Earth Resistance Tester apply to transmission line tower grounding, underground mine equipment grounding, meteorological fulmination proof grounding, petrochemical grounding, communication grounding, distribution substation grounding, railway equipment grounding, building warehouse grounding, electrical equipment grounding etc.
