Special Features:

Portable charged plate air ionization monitor with hard protective case and mounting tripod; charged plate: isolated self discharging plate of at least 15 pico farads which will discharge less than 10% in 5 minutes with 40% relative humidity and ambient ionization levels less than 200 ions/cc; power supplies for each polarity (+, -); voltage measurement: noncontacting electrostatic fieldmeter; displays: plate voltage (+, -), timer with a stop level and reset (stop level selectable at 50, 100 or 500 volts for both polarities); recorder output: 0 to 15 v using bnc connection

Properties:

An instrument which measures the electrical intensity of radiated electromagnetic energy and is usually calibrated in volts per meter or any multiple or submultiple thereof. See also fluxmeter.
