Product Codes
The GS-AQ911 is wall-mounting air quality transmitter de-
signed for use for the control of fresh air for ventilation pur-
poses. The GS-AQ911 measures the level of contaminant
gases in an air sample, and is sensitive to most heavy
odours, smoke, solvent gases etc., providing an output pro-
portional to the mixed gas concentration. This signal can be
used to control fresh air fans and dampers according to the
ventilation load. Where the primary contaminant load is hu-
man respiration, it is recommended that a Carbon Dioxide
transmitter is used.
