3M 2381 Small, Dual-Conductor, Speidel Metal Wrist Strap with 5-ft. Ground Cord

The 3M Model 724 Work Station Monitor is designed to continuously monitor the operation of the wrist strap grounding systems of two operators. To accomplish this, it uses a DC current source to measure a loop electrical resistance. The system uses a special wrist band and ground cord; 3m Wrist Bands (2368) and Grounding Cords (2360 or 2370) that contain two independent elements. The monitor uses a reliable resistance method that actually includes the operator's skin resistance to determine if the system is operating properly. If the operator's resistance exceeds pre-set levels of 10 megohms or 35 megohms, or the wiring connections exceed 3.7 megohms the red work surface lamp is lit, the green OK lamp is extinguished, and an optional alarm sounds, preventing product exposure to harmful ESD. The Model 724 also monitors its own connection to ground and the grounding of a work surface. Monitor operates on 120VAC and comes complete with AC adapter, remote dual conductor jack (Model 732), mounting hardware, and instructions.

• 3m 724 Monitor requires the use of 3m Dual-Conductor Wrist Strap and Ground Cord
• 3m Wrist Bands (2368) and Grounding Cords (2360 or 2370) must be purchased separately.

Optional stand-by jack (Model 3057) allows operator to unplug the wrist strap and move around without the alarm continually sounding. Optional dual remote splitter kit (Model 733) allows monitoring of two individuals at two separate work stations.
