The Desco 19246 Dual Operator Monitor, 120VAC continuously monitors the grounding integrity of two operators, and two ESD worksurfaces’ path to ground. The monitor will provide instantaneous notification of static control equipment failures, and eliminates the need of costly and difficult to supervise wrist strap logging record keeping. This unit is highly cost effective as it is designed to monitor any conventional single-wire wrist strap and ground cord system. The 19246 is a real time instrument that ensures that critical ESD control components in a sensitive area are effectively grounded. It independently monitors the operator and the worksurface. The instant an operator's wrist strap or cord fails, the monitor will issue audible and visual alarms alerting the user of the problem. In the same manner, the unit also confirms that a path to ground of less than 10 megohms (1 x 107 ohms) exists from the ESD protective worksurface(s).
