VOCLuftsensor.

The VOC donor captures thousands of subjects, and instead of setting limit values for all of these substances, the VOC sensor is constantly calibrated to distinguish what is background level and what are changes, that is, the addition of contaminants. In other words, it is not as easy to set absolute limit values for VOCs.
