Duct sensor CO₂ / VOC / CO₂+VOC mix

This VOC sensor automatically compensates the decrease in sensitivity by dynamic autocalibration. The reference level of air quality is derived from the ambient conditions over a 72h period. The lowest reading within this 72h time period will be used as reference level, representing the “clean and fresh air level”.

CO2 Sensors vs. VOC Sensors for IAQ What''s the ...

Unlike a CO2 sensor, a VOC sensor cannot indicate the rate of ventilation needed, only the level of VOCs in the air. It also cannot necessarily indicate whether safe or harmful concentrations of VOC contaminants are present. It can indicate a general change in the concentration of contaminants. This makes air quality sensors a better solution in applications where unusual, nonoccupantrelated ...

What do you get when you measure CO2 vs VOC

This means that the VOC levels change in step with the CO2 levels, so both measures can be used to match the ventilation system''s air turnover to the presence on the premises. An important difference, however, is that the VOC sensor also captures a number of other unpleasant contaminants, which are emitted from objects and building materials, e ...
