The Warmbier CPM74 Charge Plate Monitor is an simple-to-use device to measure air ionizers performance. Quickly and easily test ionizer decay times and offset voltage (balance) according to ANSI ESD2020 and IEC 61340-2-1.
The CPM74 is battery powered and due to its compact design, it is very suitable for the mobile use in industrial areas. It can also be operated with an AC power supply. The CPM74 is menu-driven and is controlled by with only 2 buttons for simple operation. All selected parameters will be shown in the 2 rows LCD-display for a better
orientation for the operator. The test results can also be saved into internal memory.
The CPM74 can also be used in Voltmeter mode. Measuring the voltage can be achieved either by using the plate or by disassembling the plate and using the high voltage head MK11. Direct voltage measurements can be made up to 2 kV.
