CPM-760A Collapsible 6 Inch Charge Plate Monitor Assembly

The CPM-760A is a 20pF, 6-inch Charge Plate Monitor assembly intended for use with the Prostat PFM-711A Field Meter, PCS-730 Charging Source and PDT-740B Static Decay Timer. This handy accessory is designed to perform very accurate performance audits on overhead ionizers and room ionization systems. Used with extension wings, the CPM-760A is also used to evaluate and balance bench top ionizers.

The CPM-760A is completely collapsible for compact storage in the Prostat Professional ESD Auditing Kit Series. It may be used for evaluating voltage generation and static decay performance of personnel, footwear, flooring, chairs, carts and other equipment and materials.
