- Model FM-9MA-2 - Alpha & Beta Particulate Air Monitor

From

0

The FM-9-MA2 and FM-9-MAB2 Air Monitors utilize a solid state detector and two coordinated single channel analyzer windows. Utilizing two coordinated single channel analyzers the electronics will reject Radon pulses. The sample window (PHA allows the user to preset specific energy level for sample (eg. The “Radium A” peak), measuring Pu-239 or other Alpha emitters in the presence of significant or changing Radon-Thoron background. The count rate is shown on the front panel color monitor display both rate and integrated information. The user can select the operating modes: gross count, pulse height analyzing (PHA), or PHA with background subtract (PHA-SUB).
