I recently acquired the TP09. I noticed that the VOC reading starts increasing after a while until showing an intermediate air quality. However, if I then restart the device, the sensor shows good air quality. How can I interpret this?
Attached is a screenshot showing the phenomenon. I started the device in the morning. The VOC increased slowly. The drop at around 2 pm occurred after I restarted the device.
Check the sensor ports, maybe they are blocked. The other option, possible off gassing. Restart reverted the sensors - the recording is delayed up to an hour.
Search Off Gassing on the community. Article explains it fully.
What is off gassing and what causes it?
