Ambient air quality sensors VOCs (volatile organic compounds)


The PGS-AQ series of air quality transmitters are designed for use with the control of fresh air for ventilation purposes.

They determine the air quality through measurement of Volatile Organic Compounds (VOC’s) and other mixed gases.

This signal can be used to control fresh air fans and dampers according to the ventilation load.

The -UN has a single output which automatically determines whether to run in current or voltage mode, no more jumpers or switches to worry about.
