Volatile Organic Compounds, (I believe the T stands for ‘Total’). VOCs are the chemicals that are released by (usually) human-made products that contain chemicals that are released into the air, like fresh paint, bleach, rubbing alcohol, or chemicals that are part of the product themselves, like new carpets, vanished wood or furniture, for example.

3. To measure air quality, place device in any location for at least 5 minutes for most accurate and stable readings of formaldehyde (HCHO), TVOC, and 4. After detection, turn device off and store in a cool, dry area.
Ion Science TVOC - Fixed Cal Adaptor is an alternative sensor housing allowing the TVOC to be bump tested from a remote location. Pipe connectors are attached via m5 threaded holes and gas pushed to the sensor via a gas bottle/flow regulator (sold separately). Brand: Ion Science. In Stock 7 …
TVOC should be mounted in the location most likely to detect gas. • 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
AGS02MA is a MEMS TVOC gas sensor with calibrated digital signal output. It uses special digital module acquisition technology and gas sensing technology to ensure that the product has extremely high reliability and excellent long-term stability.
