How the Laser Egg+ Chemical measures TVOC? A metal-oxide-semiconductor(MOS) sensor is used in the Laser Egg to measure TVOC concentration. To ensure measurements remain accurate throughout the sensor’s lifetime, the sensor is continually self-calibrating: the lowest reading is used as a baseline, and all given TVOC readings are relative to this baseline. For the first 5 minutes of powering ...
