Calibration of the Validation Kit

Calibration of the validation kit shall only be undertaken by Cantium

Scientiﬁc Limited. It is recommended this is done at ﬁve yearly

intervals. 

Variable area ﬂow meters impose a restriction on air ﬂow. This will

cause a reduction in the normal ﬂow of air through the MB1 and

MB2 bioaerosol samplers. Through experimentation during

development, this restriction is known at various set-points on the

tube scale and is compensated for on the ﬂow markings on the

tube.

The exact printing position on each tube is adjusted to take into

account the equivalent true ﬂow based on the known restrictions.

Once printed, the tube is calibrated for life and no further

adjustments are necessary.

Five year inspections will check the scale against the known

restrictions using the same ﬂow meter rig used during manufacture.

This rig is a calibrated secondary standard held by the glass ﬂow-

tube manufacturer.

For calibration, please arrange through your local distributor or

directly with Cantium Scientiﬁc Limited.
