SURPA 518‑2 Online ESD Wrist Strap Monitor

Purpose: A continuous-monitoring device for anti-static wrist-strap systems; monitors two operators/channels simultaneously to ensure proper grounding and warn when an operator’s strap or ground path fails. 

🔧 Key Specifications:

• Input: AC 6 V DC (via supplied adapter) 

• Power consumption: ~1.8 W Accuracy: ~1.4 MΩ ± 5% 

• Size: Typical dimension ~120 × 70 × 50 mm (varies slightly by source) 

• Weight: ~0.3 kg (or ~110 g depending on model/spec)

• Channels: Two independent inputs so two wrist-strap users can be monitored at once. 

• Alarm system: Green LED for normal operation; red LED + audible buzzer when wrist strap path breaks or resistance out of spec. 

• Accessories: Usually includes AC adapter + 2 grounding cords (one per channel)

• Materials: Plastic housing, designed for bench/workstation use. 

✅ Why It’s Useful:

• Ensures continuous real-time monitoring of the wrist strap + ground path rather than just a one-time test. This helps prevent ESD damage to sensitive electronics at your workstation.

• Dual channel means you can monitor two operators at the same time — helpful if your service/repair desk or electronics workstation has multiple persons.

• Compact and designed for mounting on or near the workbench; doesn’t take up much space.

• Visual + audio indicators make non-compliance immediately noticeable (green vs red + buzzer) so operator can act quickly.

• For your business (you do e-commerce + service of electronics) this is a good addition for your in-house testing/repair environment or if you sell/handle ESD-sensitive products.
