VOC Index for Experts

The VOC Algorithm constantly estimates sensor baseline and sensitivity from statistical data of the past 24 h. For this reason, multiple VOC Index signals are most similar if history is equal since startup. When placed into a common room but with different histories, all VOC Index signals usually converge within 1 to 12 h. Figure: Three sensor modules with different histories converge after ...

vocs sensor

Both sensor types are nonselective which means they can be used for measuring a wide variety of VOCs. To achieve this they have been calibrated against isobutylene that allows them to respond to a wide range of VOCs at varying degrees of sensitivity. Each type has a calibrated measurement range against a set of VOCs. PID type VOC sensors are more resilient and can detect a wider variety of VOCs.
