Electrostatic Field Meter

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.

BENEFITS

SPECIFICATION


Display	3-1/2 digit Liquid Crystal Display with 0.4″ digit height. Automatic polarity, HOLD and LOW BATTERY indicators.
Range	High Range 0 V to ± 19.99 KV; least significant digit indicates 10 volt at one inch distance. Low Range 0 V to ± 1,999 V; least significant digit indicates 1 volt at one inch distance. Measures higher voltages at greater distances, e.g., at two inches double indicated voltage, at four inches multiply indicated voltage by four.
Accuracy & Environment	± 5% at ambient conditions ( 23ºC and 30% Rh). ± 5% at 0 – 50ºC and 0 – 85% Rh (non-condensing). Accuracy unaffected by the presence of air ionization.
Dimensions	27.2 mm x 61.5 mm x 105.9 mm.
