Technical Specs



A Complete Instrument Set for Electrostatic Measurements

Prostat’s innovative PFK-100 set was the first instrument combination of its kind. It includes Prostat’s unique PFM-711A dual range field meter, the original CPM-720A portable 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.


Locate and Measure Static Charge

The battery operated PFM-711A Field Meter is a compact stabilized “electronic chopper” design with accuracy of ±5% at ambient conditions (23ºC and 30%Rh). This advanced design allows it to be used in ionized environments without drifting. It features automatic polarity indication, a 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. The PFM-711A offers the user two ranges of operation:

  • 0 – 1,999V in 1 Volt increments with <±5% error, and
  • 0 – 20,000V in 10 Volt increments with <±5% error up to 5kV

With the supplied analog output cable, it can be used in conjunction with an X-Y plotter or any analog data-recording device. The front panel analog output jack provides a 1 volt output corresponding to 10kV, which is independent of the selected meter range and indication.


A Portable Charge Plate Monitor

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 SP3.3 Periodic Verification, voltage or charge generation and voltage suppression analysis.Performace studies indicate the CPM-720A 3.25 inch plate has a strong correlation to the CPM-760A 6 inch Charge Plate Monitor.


Charge It Up!

The PCS-730 ±1 kV Charging Source is used to charge the CPM-720A to ±1,000 volts to measure ionizer decay time as required by both ANSI/ESD S3.1 and ANSI/ESD SP3.3.These three instruments are match calibrated to work together for accurate and efficient auditing.


Use it with an X-Y Plotter, Strip Chart Recorder or Digital Logging device
The PFK-100 Field Meter Set can be used for voltage generation and decay analysis in conjunction with a variety of data recording instruments. Prostat’s PGA-710B Autoanalysis System® is a most unique electrostatic data analysis device. It records, plots, analyzes and automatically constructs reports of body voltage generation, electrostatic decay, voltage retention, ionizer performance and other static measuring functions. The combination of Prostat’s PFK-100 Set and PGA-710B Autoanalysis System® is the most up to date instrument collection for meeting today’s ANSI/ESD S20.20 and IEC 61340-5-1 ESD Program standard requirements.
