The hand-held PFM-711A Fieldmeter is an instrument used to perform static surveys and polarity on objects with accuracy of ±2% at ambient conditions (23ºC and 30%Rh). This stabilized chopper can be used in environments with a presence of ionization without drifting. The Hold button allows the field meter to hold the measurement for easy recording. It also features automatic polarity indication, 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 includes two ranges of operation:
0 to 1,999V in 1 Volt increments with <±2% error
0 to 20,000V in 10 Volt increments with <±5% error up to 5kV
The CPM-720A Charge Plate Monitor is an accessory that attaches to the PFM-711A Field Meter. When attached, the system will allow to balance ionizers per ANSI/ESD SP3.3, voltage or charge generation and voltage suppression analysis.
