AIR SAMPLER(MICROBIAL AIR MONITORING SYSTEMS)How the HKM-II worksMicrobial Air Monitoring Systems are sieve impaction systems based on theAnderson impaction principle, accepted and proven world-wide. Air is aspirated through a perforated lid with 488 holes. A radial fan, controlled by a flow sensor, accurately regulates air flow real time at 100 liters/min. The air is impacted onto the surface of growth media in a 90mm Petri dish. Microorganisms impact the media and the colonies are counted after the proper incubation period. All HKM-II microbial air samplers comply with the guide lines as specified in ISO14698-1.Sample collection accuracyThe HKM-II Microbial Air Monitoring Systems provide the most accurate samplecollection available. The HKM-II utilize a state-of-the-art mass flow sensor to assure a constant air flow rate of 100 liters/min. The mass flow sensor continuously regulates the air flow rate during sample collection. This allows the HKM-II system toautomatically adjust for differences in fill volume of Petri dishes, changes in air density and differences between individual perforated lids.Technical SpecificationsNominal Airflow: 100Liters/minHeight: 33cmWeight: 2.6kgMaterial: High Quality AerialaluminumDiameter of Applied Petri dishes: 90mmError Range: 2.5%Freely Definable Sampling Volumes: 1 to 6000 LitersDisplay: Alphanumeric Liquid Crystal DisplayPower Unit/Battery Charger: 110-240 volt, 50-60 Hz
