Introduction
Aeroqual’s gas sensor calibration can be adversely affected by the very dry (dew point < -20oC ) air generated by third-party calibrators.
If you’re using a third-party calibrator with a dry zero air source or a cylinder of zero air, you’ll need to humidify the calibration gases before they’re delivered to your Aeroqual monitor. Aeroqual supplies a calibration humidifier as part of the AQM 65 service kit. It contains a nafion membrane from Permapure, which allows the transport of water molecules across the membrane with high selectivity and no loss of calibration gases.
Note: If you’re using an AirCal 8000 or an AirCal 1000, you don’t need to use a calibration humidifier to calibrate Aeroqual gas modules. These calibrators are specially designed to optimally prepare the calibration gases for this monitor.

Parts
-
-
Fill the humidifier with water to the top of the label covering the black internal tubing.
-
-
-
Place the humidifier between the outlet of the third-party calibrator and the gas inlet of the monitor.
-
To allow excess gas to vent, open (uncap) the tee on the gas inlet.
-
Set the flow rate through the humidifier to be between 3 and 5 LPM.
