Gesundheit: Beurteilung nach dem TVOC-Konzept

· Vor diesem Hintergrund kann das TVOC-Wert Konzept (TVOC, total volatile organic compounds) als Bewertungsmöglichkeit herangezogen werden. Grundsätzlich ist ein solches Konzept nicht toxikologisch begründet und kann daher nicht direkt als ein Kriterium zur Beurteilung gesundheitlicher Wirkungen herangezogen werden.

How Does a TVOC Sensor Actually Work? - Kaiterra

What the sensor is actually measuring is the electrical resistance of this metal-oxide 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 …
