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

Thus, a measurement known as TVOC was adopted to measure the overall amount of VOCs in a given space. Total volatile organic compounds (TVOC) is a group of VOCs used to represent the entire pool of pollutants. If you have an air quality monitor with volatile organic compound detection capabilities, you will see your readings in terms of TVOC.

How Does a TVOC Sensor Actually Work? Kaiterra

MOS (metal oxide semiconductors) work by heating a thin film, or surface, of metaloxide particles. In Kaiterra products, this is a thin film of metaloxide nanoparticles. This film is heated to around 300’C (hence the warm up period after turning on a Kaiterra device). During operation, oxygen particles will be adsorbed on the surface, and ...
