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 ...
