TRONOVO MM322 Dual-Station Wrist Strap Online Monitor

The TRONOVO MM322 is a dual-station online monitor designed for continuous supervision of two dual-loop or dual-wire wrist straps. It detects resistance outside the preset limits and provides an audible alarm with a flashing warning, helping operators respond quickly to grounding faults at ESD-protected workstations.

Adjustable monitoring thresholds, status-signal output and a durable SUS304 stainless-steel housing make the MM322 suitable for electronics manufacturing, cleanrooms and other workplaces handling electrostatic-sensitive devices. Continuous monitoring reduces dependence on periodic manual checks while supporting consistent operator-grounding control.

Key Features

• Two monitoring stations: Supervises two operators or wrist-strap connections from one compact unit.
• Dual-loop wrist strap support: Provides continuous monitoring for dual-loop and dual-wire personnel-grounding systems.
• Adjustable monitoring value: Supports a 0.75MΩ–10MΩ/35MΩ adjustable range for different workplace control requirements.
• ±10% accuracy: Delivers consistent resistance supervision for routine ESD workstation monitoring.
• Fast fault indication: Responds in under 0.1s with audible and flashing warnings when the monitored resistance exceeds the preset limits.
• Remote alarm capability: The operating-status signal can connect to an external warning light or monitoring network.
• Equipment interlock support: The output signal can be used to control the start and stop of high-voltage equipment within an engineered safety workflow.
• SUS304 stainless-steel housing: Provides a robust, hygienic enclosure suitable for production and cleanroom environments.
• Quiet operation: Monitors continuously without introducing operational noise at the workstation.
• Optional customized relay output: Supports system integration when the customized relay configuration is specified.

Applications

• Electronics assembly and PCB production workstations
• Semiconductor manufacturing and handling areas
• Cleanroom ESD personnel-grounding control
• Production lines working with electrostatic-sensitive devices
• Workstations requiring external alarms or equipment interlocks

Why Choose the TRONOVO MM322?

The MM322 is intended for facilities that need continuous dual-loop wrist-strap monitoring for two stations in a compact, durable enclosure. Its adjustable thresholds, rapid warning response and external status output support immediate fault awareness and practical integration into ESD control processes.
