A real-time multi-point ground resistance monitoring device is provided herein to simultaneously monitor ground resistances of different work stations. The present invention mainly contains a number of monitoring ports connected to multiple test ground points in parallel via conductive wires respectively. Each monitoring port is configured with a safety range of acceptable ground resistances and a presentation manner of the alarm when the measured ground resistance of a monitoring port exceeds the safe range. The monitoring device has a self-correction function to automatically offset the resistance of conductive wire from the measurement result when the conductive wire is too long. The monitoring device can further contain a network interface allowing remote operation and monitoring.
