The HD-GDZJC/10 online transition resistance monitor is a new high-tech product developed by our company for transition resistance monitoring. It is specially used for online monitoring of transition resistance between metal components and connecting conductors of grounding grid electrodes. The transition resistance measurement adopts the Kelvin four-wire test method. Equipped with an RS485 communication interface and supporting Modbus RTU protocol, the monitor allows users to conduct secondary development, build networks and realize remote multi-point online monitoring based on the communication protocol. Featuring simple installation, compact structure, safety and durability, it is widely used in central computer rooms, power systems, railways, transportation systems and other scenarios.
