ESD Tester Checker for Wrist Strap Grounding System in Cleanroom and Electronics Factory
ESD Wrist Strap Tester is a reliable static control device designed to check the grounding performance and electrical connection status of ESD wrist straps before operators enter electrostatic sensitive areas. It accurately measures wrist strap resistance and quickly identifies whether the grounding system is functioning properly, helping protect sensitive electronic components from electrostatic discharge damage.
Designed for semiconductor manufacturing, electronics assembly, PCB production, laboratories, and ESD-controlled cleanroom environments, this tester provides a fast and efficient way to verify operator grounding conditions and maintain effective ESD protection management procedures.
Normal grounding connection: The tester detects a stable wrist strap grounding system, with no alarm sound and the green indicator light illuminated.
Grounding failure status: When the wrist strap connection is broken or the grounding resistance is abnormal, the tester activates an audible alarm and the red indicator light flashes to alert the operator for inspection and correction.

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
SMT/PCB Assembly： Ensures operators are safely grounded during PCB handling and soldering processes.
Mobile & Device Repair： Protects sensitive components such as ICs and displays during repair operations.
Laboratory & Calibration： Provides stable grounding protection for sensitive electronic testing equipment.
Cleanroom Manufacturing： Supports reliable static control in controlled production environments.
