For monitoring and analysing microbial contamination in the air, especially in sensitive hygienic areas. Operates according to the impaction principle: Aspirated air meets a culture medium to which microorganisms adhere. The subsequent cultivation in the petri dish shows the microbiological load. Application: pharmaceutical industry (monitoring the number of microorganisms under the laminar flow hood; analysing the cleanliness of a clean-room; testing the effectiveness of sterilisation), food and beverage industry (detection of microbial contamination in the clean-room according to the HACCP concept), hospitals (detection of pathogenic microorganisms in operating theatres, pharmacies, storage rooms or intensive care units), electrical industry (measurement of particles and microbacterial contamination in clean-rooms) Collection head with 300 pores (Ø 0.6 mm), sterilisable; can be used with standard Petri dishes Ø 90 x 13-15 mm; acc. to ISO 14698-1 Volume can be adjusted freely (in 10-litre increments) Option for continuous measurement or cyclical sampling; pause time (max. 99 min.) and number of cycles (max. 99) are also defined here 99 memory spaces for individual setups; 4000 measured values with date, time and volume are saved per memory space; data can be called up on the device Choice of battery or mains operation; with audible alarm in the event of a power outage Airborne germ collector PCE-AS1 Delivery incl. adapter for glass petri dishes with calibration attachment, carrying case, rechargeable battery (7.4 V/Li-Polymer) and mains plug.
