Charged plate monitor with plate electrode and battery operation - A1-ESD EP0201082

The CPM 8374B charged plate monitor verifies the effectiveness of air ionisers directly at the workstation. Using the integrated plate electrode (150 x 150 mm) it determines the offset voltage and the decay time from a pre-selected threshold to a lower value (default +/- 1000 V to +/- 100 V), making the neutralising performance of the ioniser traceable.

Benefits

• Built-in electrostatic field meter on the field-mill induction principle with high input impedance of 10¹⁵ ohm
• High-voltage unit isolated through high impedance and therefore safe to touch
• Mains or battery operation for stationary and mobile use
• Menu-guided two-button operation with two-line LCD display
• Reading storage in internal EEPROM, readout via RS 232
