The BA/AQS Series indoor air quality sensors are designed
around a unique oxidizing element that varies in resistance with respect to
the contaminant gases it contacts. The sensor is non-specific to any one gas.
Instead, the output signal corresponds to the combined concentration of over
30 contaminant gases, typically found in indoor environments. The BA/AQS
Series is offered in wall or duct mount, with 0-5VDC or 0-10 VDC outputs.
As part of an overall air quality control scheme, this sensor can be used
to detect circumstances that require varying amounts of ventilation.
