BulletPoint1 : ETCR2900 Online Earth Resistance Tester is our company devotes ourselves to Grounding resistance test technical research’s another high-tech product for more than ten years. Adopting precise 3-wire or simple 2-wire method for ground resistance measurement, average value rectification method for ground voltage measurement online testing and real-time monitoring. The user can select RS232 or RS485 communication, according to the protocol MODBUS, the user also can proceed secondary development,
BulletPoint2 : ETCR2900 Online Earth Resistance Tester apply to transmission line tower grounding, underground mine equipment grounding, meteorological proof grounding, petrochemical grounding, communication grounding, distribution substation grounding, railway equipment grounding, building warehouse grounding, electrical equipment grounding etc
BulletPoint3 : Three excellent functions: sound and light alarm function, data storage function, data retention function.
BulletPoint4 : Precision clamp head design: using precision iron core and winding, stable, precise and strong anti-interference.
BulletPoint5 : Easy to use: When measuring a grounded system with a loop, there is no need to disconnect the ground lead and no auxiliary electrode.
