How Does a TVOC Sensor Actually Work?

What the sensor is actually measuring is the electrical resistance of this metaloxide layer. This real time measurement and output of resistance is the first step in obtaining our TVOC reading. The change in resistance across the surface of the sensor is directly proportional to the change in concentration of the target gas(es). The exact degree to which the resistance will change (that is, the ratio or equation that …


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.
