Aeroqual calibrators

The Aeroqual AirCal 1000 is a portable calibrator you can transport to the monitor along with gas cylinders and set up onsite and then remove from site after calibration.

The outlet flow rate of the AirCal 1000 is fixed at approximately 2.5 LPM which means you can use it to calibrate more than one monitor simultaneously.

The AirCal 1000 has two gas inlet ports (⅛ Swagelok compression) and one gas outlet port (¼ Swagelok compression). It comes with all the necessary tubes and fittings.

Aeroqual recommends you use its optional gas regulator with the AirCal 1000.

The AirCal 1000:

• has an internal integrated zero air generator for zero calibration
• can be used to zero calibrate ozone, but not for ozone span calibration
• can’t be used to zero or span calibrate CO₂
• isn’t IP rated, so you need to take care when operating outdoors.

For learn how to operate and maintain the AirCal 1000, see here.

The AirCal 1000 can be used to zero calibrate ozone, but not for ozone span calibration. For ozone span calibration, Aeroqual recommends (and sells) the Model 306 Ozone Calibration Source made by 2B Technologies.

Aeroqual refers to the Ozone Calibration Source as the O3Cal - a light, portable ozone calibrator you can easily carry onsite for ozone span calibration.

Tubing and gas fittings aren’t supplied with the O3Cal but can be ordered separately.

The O3Cal isn’t IP rated, so you need to take care when operating outdoors.

Ozone Calibration Source user guide

The Aeroqual AirCal 8000 is an (optional) integrated calibration system where the gas cylinders and calibration system are permanently installed in the AQM 65. It’s an excellent option if frequent calibrations are required, or your AQM 65 is installed a long way from the service engineer's location.

Gas cylinders are stored in a compartment on the left side of the main enclosure, and the components that perform the calibration are in a module inside the main enclosure.

The module can be scheduled to deliver calibration gas automatically, or it can be manually triggered remotely using Aeroqual Cloud without the need for an engineer to visit the site.

The AirCal 8000 comes with two regulators and all the necessary tubes and gas fittings. It doesn’t include calibration gases. These must be purchased locally.

The AirCal 8000 can be added at the time of purchase, or it can be added later (retrofitted) in the field.

The AirCal 1000 and AirCal 8000 are shipped with all the tubing and fittings you need to calibrate your gas modules. Both use imperial-size tubing and Swagelok compression fittings (stainless steel ¼ and ⅛ ).

The outlet on the gas regulator is a ⅛ Swagelok compression fitting. The inlets on the AirCal 1000 and AirCal 8000 calibrators are also ⅛ Swagelok compression fittings. The maximum inlet pressure is 50 PSI.

The tubing that connects the regulator to either calibrator is ⅛ OD PTFE.

The outlet on the AirCal 1000 and O3CAL is a ¼ Swagelok compression fitting. The gas inlets on your Aeroqual AQM 65 and AQS 1 are also ¼ Swagelok compression fittings.

The tubing that connects the AirCal 1000 and O3Cal to the monitor (via a tee) is ¼ OD PTFE tubing. When connecting the AirCal 1000, the tee is uncapped (as shown). When connecting the O3Cal, the tee is capped.

If needed, you can order extra ¼ and ⅛ OD tubing for connecting the gas regulator to the calibrator and the calibrator to the monitor from Aeroqual.
