MAS-100™ is a professional microbial air monitoring system developed and produced by MBV AG in Switzerland. It is suitable for detecting microorganisms in the air.
The MAS-100™ is a high‑performance microbial air monitoring instrument that draws 100 L of air per minute and deposits airborne microorganisms onto standard Petri dishes. It follows the Andersen impaction principle and complies with ISO 14698‑1 for clean‑room monitoring. The manual explains the basic principle, safety considerations and the advantages of the device.
The guide details all operating functions: turning the unit on and off, selecting manual, template or selectable sampling modes, adjusting volumes (1‑2000 L), using the delay function, calibrating the instrument, and connecting a printer. It also provides maintenance tips, battery handling, and a full list of technical specifications.
