How Does a TVOC Sensor Actually Work? Kaiterra

VOCs are important indoor air pollutants that negatively impact our health. We''ve talked about what exactly VOCs are in our previous post, and now we are facing another key question: how are VOCs measured, or how does a TVOC sensor work?. There are a number of ways to measure VOCs, with pros and cons based on the situation, budget available, etc. Historically, laboratory techniques such as ...

Performance of optimized TVOCs sensor ScienceDirect

01/01/2010· The response time of TVOC sensor was usually determined by the rate at which the sample was pumped through the detection chamber and flushed out completely. Here the standard gas of benzene at 10 ppm was used to determine the response time of PID, which was defined as the time that the PID took to get a stable response to the sample. The response time of perpendicular PID (~ s) …
