Overview

The PFK-100 set includes Prostat's unique PFM-711A dual range field meter, CPM-720A charged plate monitor assembly and PCS-730 ±1 kv charging source. With this instrument set you can measure electrostatic fields, analyze ionizer performance and assess the voltage generation of materials, equipment and personnel.

The battery operated PFM-711A Field Meter is a compact "electronic chopper" design with accuracy of +/- 2% at ambient conditions (23oC and 30%Rh). It features automatic polarity, measurement "hold" button, low battery indicator, high and low ranges, distance ranging lights for accurate and repeatable measurements, manual zero control and a ground snap. With the supplied analog output cable, it can be used in conjunction with an X-Y plotter or any analog data-recording device.

The CPM-720A Charge Plate Assembly is 3.25 inches square. It attaches to the PFM-711A field meter for ionizer balancing per ANSI/ESD-S3.1, voltage or charge generation and voltage suppression analysis.

The PCS-730 +/- 1 kV Charging Source is used to charge the CPM-720 to +/- 1,000 volts to measure ionizer decay and material decay. These three instruments are match calibrated to work together for accurate and efficient auditing.
