How Does a TVOC Sensor Actually Work? Kaiterra

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 …

TVOC Manual Gastech

• TVOC must be mounted vertically with the sensor underneath the case. This avoids dust and debris blocking the access to the detector cell. • Mount TVOC higher if detecting VOC gases that are lighter than air or lower if detecting VOC gases that are heavier than air (but never on the floor). This should maximise detection. • Mount TVOC in an area that has good air circulation ...
