Equipment Ground Monitor

The real-time grounding monitoring system integrates cutting-edge technologies and compliance requirements of ANSI/ESD S20.20 standard, breaking through the single-function limitations of traditional equipment. It covers full-scenario monitoring of equipment grounding, anti-static wrist straps, anti-static work mats and equipment leakage. One unit can replace multiple single-function monitoring devices, effectively reducing procurement and maintenance costs, and perfectly meeting the standardized ESD control requirements of production workshops.

Product Features:
• Multi-channel integration, one device for multiple workstations
• Second-level alarm for broken wires, disconnections and out-of-limit values
• Monitor both resistance and voltage
• Reminder upon operator arrival, auto standby after leaving
• Power supply enabled only when qualified, auto power-off on departure
• Immediate alarm and lockout if ground wire is disconnected

Multi-function Design for Cost Reduction & Efficiency Improvement

4-channel dual-loop wrist strap + 4-channel work mat + 4-channel equipment grounding + 1-channel main equipment grounding. No module replacement required, unified alarm and unified backend access.

Triple Real-time Alerts

Periodic testing only proves the status "at the moment of testing". Broken cables or disconnections between tests rely purely on luck. Expose abnormalities the second they occur, instead of waiting until the next shift inspection.

Simultaneous Detection of Resistance & Leakage Voltage

Synchronous monitoring of equipment grounding resistance and AC/DC residual voltage. Customizable threshold values with audible & visual alarms upon limit violation.

Protection Activates When Operator Checks In

Infrared sensor automatically detects operator arrival. Buzzer + red light prompts wrist strap wearing; red light turns green once wearing passes check for access permission. Auto standby on leaving, no false alarms for brief passers-by.

Power Supply Activates Once Protection Is Ready

Power supply enabled only when wrist strap, work mat and equipment grounding all pass inspection. Auto power-off upon leaving, compliance and energy saving achieved in one step.
* The qualified release combination can be adjusted according to site conditions

Block False Grounding Instantly

Real-time monitoring of main equipment grounding resistance and voltage. Immediate display, lockout status and audible-visual alarm for disconnected ground wire — false grounding changes from self-discipline to system enforcement.

Fully Compliant with International ESD Standards

Supports system certification: continuous grounding monitoring required by ANSI/ESD S20.20 and IEC 61340-5-1. 13-channel full-time online monitoring for TM4512 wrist straps, work mats and equipment grounding
Reduced daily maintenance: continuous monitoring replaces daily plug-unplug tests. Alarms and status records are auto-generated, eliminating manual inspections and paper logs
Smooth factory audits: verification data is continuously logged and retrievable on demand, ready for presentation during audits and inspections by premium customers
