Máy đo tĩnh điện Prostat PFK-100, PFK-100B
3-1/2 digit Liquid Crystal Display with 0.4" digit height. Automatic polarity, HOLD and LOW BATTERY indicators.
OUTPUT
Analog signal output and 30 inch two conductor cable provided. ± 10.0KV meter reading equals ± 1.0 volts output.
RANGE
High Range 0 V to ± 19.99 KV; least significant digit indicates tens of volts 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.
RANGE LIGHTS
Red "Bulls Eye" at one inch distance
ACCURACY & ENVIRONMENT
± 2% 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.
