Refer to the user's guide accompanying the instrument.
Carbon dioxide is quantified in the field with a direct-reading instrument (DRI).
The minimum reported value is 18 mg/m³ (10 ppm). The reference method
corresponds to calibration of the DRI.

Refer to the user's guide accompanying the instrument.
Quantification of carbon monoxide is done in the field with a direct-reading
instrument (DRI). The minimum reported value is 1.1 mg/m³ (1 ppm). The
reference method corresponds to calibration of the DRI.

For the monitors, the flow must be considered as being a sampling rate.
According to the data from 3M, the precision (CVsampling) of the sampling rate is
1.3%. Refer to the 3M passive monitor guide on the IRSST's Web site.

Sampling of respirable dusts is also possible by using the flow rate appropriate to
the cyclone used.
Additional information is available in Info-Labo 91-03. The weight measurement
method for dusts is by definition non-specific.
