PCE-AS1 is an air sampling meter used to assess microbiological pollution and monitor hygiene. Designed for use in hospitals, clean rooms and food and beverage, cosmetics and pharmaceutical production facilities, the PCE-AS1 Measuring device for cleanrooms meets the latest requirements for devices used for airborne microbial analysis. Optional ISO calibration lab certificate as an accessory.

The PCE-AS1 Measuring device for cleanrooms uses the aerosol impaction principle or Andersen collision principle to assess air quality.  The air taken in at the top of the instrument is pulled through 300 micropores and the resulting laminar air flow is directed onto the surface of an agar petri dish.  When the sampling cycle is complete, the petri dish is removed and incubated.  The bacterial and fungal counts can then be assessed in accordance with USP 797 and CAG-009 guidance.
The collecting head should be sterilized in an autoclave at 121° C for 30 minutes (sterilization with a cloth with 75% alcohol is also possible.)  The petri dish should also be sterilized with 75% alcohol.
