Electrostatic Field Meter Set

Uses a Chopper-Stabilized Sensor
The PFM-711B is an accurate, portable electrostatic field measuring device that is easy to use and designed for one hand operation. The PFM-711B is a digital, electronic chopper design, which allows the instrument to make electrostatic field measurements in areas where ionized air is present. Used by itself, the PFM-711B will measure electrostatic fields emanating from virtually any flat surface or object.

Measure in 1 Volt and 10 Volt Increments
The PFM-711B uses a dual range for measuring surface voltage and electrostatic potentials in both positive and negative polarity charges. In the kV/Inch range, the PFM-711B will indicate electrostatic field voltage from 0 to ±20,000 volts in 10 volt increments at 1″ (25mm) distance from the charged surface. In the V/Inch range, the field meter measures field density from 0 to ±1,999 volts in 1 volt increments at 1″ (25mm) distance from the charged surface. The instrument is easy to use and its controls are designed for one hand operation.

Portable Charge Plate Monitor
The CPM-720B Charge Plate Assembly is a 3.25″ x 3.25″ isolated plate attachment for the PFM-711B Electrostatic Field Meter. It converts the PFM-711B Field Meter into a portable, battery operated charged plate monitor. By attaching a CPM-720B Charge Plate to the PFM-711B, the meter can also be used for Ion Balance voltage measurements.

Charge It Up!
The PCS-730B can be used to place a ±1000V charge on the CPM-720B Charge Plate making it possible to also measure the discharge times of air ionization equipment per ANSI/ESD SP3.3 Periodic Verification of Air Ionizers.
