This Spartan One constant monitors provide ongoing testing of single wire wrist straps and ESD worksurfaces. The CM300 not only eliminates time consuming wrist strap testing, it removes the danger of wrist straps failing in the field and possibly exposing highly sensitive materials to static. Both audible and visual alarms signal when the wrist straps fail. Enclosed in a durable metal case with built in mounting brackets, the monitors can be installed underneath table tops to save work space. The CM300 series monitors meet or exceed the recommendations of ANSI ESD S20.20.
