Defining TVOC: Why TVOC Is So Difficult To Explain

While a TVOC sensor may be responsive to many thousands of VOCs, the output can be adjusted or set so that a ppb output can be mapped to a defined mix of gases. Kaiterra products are designed to accurately represent the Typical IAQ Mix as defined by Mølhave et al. This provides an excellent representation of the typical indoor environment, and ...

Understanding TVOC: What You Need To Know About Volatile ...

The heating of oil during cooking can make your TVOC readings skyrocket. With an air quality monitor, you can spot trends in your TVOC readings and even discover potential sources of VOCs. For example, TVOC readings often increase sharply during cooking; many cooking sprays and heated oils will produce VOCs. With an air quality monitor, you will know when it is best to vent out VOCs and which ...

How does Atmotube VOC sensor work?

SGP sensors are calibrated with ethanol, which serves as a reliable and economical proxy for TVOC. This can be verified by comparison between the reponse of the SGP to ethanol and to an ISO normed two kinds of VOC gas mix that represents TVOC. Within a large target gas concentration range, the SGP reveals a similar gain for both of those target gas compounds (compare similar slopes in Figure ...
