Validating the MB1 or MB2 bioaerosol sampler
Calibration and validation should be carried out in a controlled
environment and on a level surface.
Air movement around the
calibration zone should be eliminated and ideally carried out in
normal atmospheric pressure of 1013 mbar at 20°C.

Switch on the air sampler and set to take a volume of 400 litres.
This will allow sufficient operating time for validation/calibration to
be performed. Now start the sampler.
NOTE: MB2 users will need to initiate sampling operation before
fitting the validation rig to the MB2 sampler.
