RAS for reliable and reproducible protection degree determination

Applications
  • Protection degree determination in operating rooms as per SWKI 99-3 and DIN 1946-4
  • Clean room acceptance tests
  • Calibration of measuring devices with the RAS 3000 C
The necessary reference concentration can be adjusted reliably and reproducibly to Cn,Ref = 106 particles/ft3 = 35.3 • 106 particles/m3 for the generation of the reference source flow QRef = 6.3 • 109 particles/min as per SWKI 99-3 and DIN 1946-4.

The RAS comprises an aerosol generator and an aerosol distributor with six aerosol outlets and up to six sampling heads. The highly accurate aerosol concentration is obtained by means of a special aerosol generator and one mass flow controller each for the volume flow on the aerosol generator and for the mixed air supply.
