Products Details
Why Choose the SURPA-9202D?
Simultaneous Dual-Path Monitoring: Most monitors only check the person. The 9202D checks the Operator AND the Mat. If your mat's ground wire becomes loose, the "BENCH" alarm will alert you immediately.
Compact Footprint: At only 61mm wide, it fits perfectly under shelf brackets or on the corner of a workstation without obstructing the assembly area.
Instant Audible Warning: No need to constantly watch the lights. If a wrist strap is worn too loosely or a wire snaps, a loud buzzer sounds instantly, stopping a potential ESD event before it happens.
Strong Anti-Interference: Optimized circuitry prevents "false alarms" caused by electromagnetic interference from nearby soldering stations or power tools.
Compliance Ready: Designed to help your facility meet GB/T 15463-2018 and JJF(津)101-2023 requirements for continuous monitoring.
application
