Suggested CO Control Sequence Of Operation

Multiple Sensors Controlling a Single AHU: Control should be based on the highest CO 2 concentration measured in all spaces served by the air handler. This can be accomplished within the programming capabilities of most building control systems. Alternatively, transducers are available that can take in multiple inputs and pass through the highest value. Contact AirTest for recommended vendors ...

Data Harvest | Carbon Dioxide Sensor Learn more

The sensor uses absorbance of infrared energy by CO2 to measure levels (the more infrared light is absorbed the greater the concentration of carbon dioxide). This sensor is for measuring gases – not liquid CO2 concentrations. Liquid will permanently damage the Carbon Dioxide sensor. If the sensor is to be used in an environment where there is a risk of condensation with a plant in a ...
