– AS 4000 and AS 4500 

The AS 4000 and AS 4500 allow for aerosol and iodine sampling using cartridges and paper filters. These samplers trap particles and iodine in atmospheric discharge ducts or ventilation extraction ducts. The AS 4000 and 4500 have numerous functions, such as regulating the sampling flow with standardized air flow or measuring the clogging of filters with adjustable alarm thresholds.
