TRONOVO MM311 Single-Station Wrist Strap Online Monitor

The TRONOVO MM311 is a single-station online monitor for continuous supervision of a single-loop or single-wire wrist strap. It provides real-time warning when the operator-grounding path moves outside the set monitoring condition, helping production teams identify wrist-strap faults before electrostatic-sensitive products are exposed.

Its adjustable 0.75MΩ–10MΩ monitoring range, self-locking operation and external status-signal output support consistent ESD workstation control. The compact SUS304 stainless-steel enclosure is suitable for electronics manufacturing, cleanrooms and other environments requiring reliable personnel grounding.

Key Features

• Continuous single-station monitoring: Supervises one operator wrist strap throughout the work process instead of relying only on periodic testing.
• Single-loop and single-wire support: Designed for common single-wire wrist-strap grounding systems.
• Adjustable monitoring value: The 0.75MΩ–10MΩ sensitivity range can be configured for the workstation control requirement.
• Rapid warning: Responds to an abnormal grounding path in under 0.1s for prompt operator attention.
• Self-locking operation: Helps prevent unintended shutdown while the wrist-strap connection remains engaged.
• Local status indication: The front LED and alarm provide immediate workstation feedback.
• Remote status output: The operating signal can connect to an external alarm light or monitoring network.
• SUS304 stainless-steel housing: Provides a durable and hygienic enclosure for production and cleanroom use.
• Compact installation: The 104×58×27mm body and mounting flanges simplify placement at an ESD workbench.
• Quiet operation: Supports continuous monitoring without adding operational noise to the workstation.

Applications

• Electronics assembly and PCB production workstations
• Semiconductor device handling and packaging
• Cleanroom personnel-grounding control
• Repair, service and quality-control benches
• Workstations requiring external status indication or networked alarms
