This mini monitor is a single workstation continuous monitor. It continuously monitors the path-to-ground integrity of one operator and one ESD work surface. The monitor eliminates the need for periodic testing and record keeping of wrist straps. Designed with Wave Distortion Technology which provides stable continuous monitoring of the path-to-ground and presence of 1 megohm resistance of an operator’s wrist strap. Audio and visual alarms activate (in less than 50 milliseconds) when the operator unintentionally disconnects from the monitor or the wrist strap connection points are intermittent. The monitor also serves as a ground point for an ESD worksurface and monitors for a path-to-ground of less than 500 megohms. Comes calibrated to NIST standards and include a certificate.
Fail low alarm - all standard wrist strap testers include a fail low setting. This is important for operator safety. If the wrist strap is missing a resistor or has a defective resistor, the operator will be in effect plugging directly into hard ground (the resistance of the monitor is only 40K ohms). Using a monitor like the Desco 19239 / 19242 keeps your operators safe and your company's liability to a minimum.
Parking snap - allows you to keep the coiled cord at the monitor which helps prevent cord from getting lost, prevents cords from wearing out (a cord should not have to be unplugged once it's in the monitor and parked). You'll need to buy fewer cords, saving you money and should allow you to use less expensive cords due to less wear and tear on the banana plug and the strain relief.
