Product Overview
BAI 9109-4
- The Beta-Gasmonitor BAI 9109-4 provides the opportunity to monitor radioactive gases such as Krypton-85, Argon-41, Xenon-133, Carbon-11 and Fluorine-18 in rooms and discharged air with low minimal detectable activities.
- The sample air being measured will be directed via a prefilter by means of a pump disturbing particles within the sample air will be removed and the air will be directed to the measuring chamber.
- The measuring chamber has a volume of 11.45 l and is equipped with a lead shield all sides with 2 cm thickness in 4π geometry to minimize the background as much as possible.
