About This Product
BAI 9109-4 has a low detection limit and can also measure radioactive gases such as Kr-85, Ar-41, Xe-133, C-11, and F-18 in indoor air and exhaust gas. The measuring chamber can be equipped with 1 to 4 xenon-sealed large-area proportional counters, allowing one detector to be used as a compensation detector.
The air to be measured is pumped into the measuring chamber via a prefilter. The measuring chamber has a volume of 11.45 l and is fully equipped with a 2 cm thick lead shield in a 4π geometry to minimize background as much as possible.
