How does Atmotube VOC sensor work?

Calibration of Atmotube TVOC Sensor. The Sensirion SGP is a broadband VOC detector, which is capable of detecting various VOCs and therefore TVOC. Sensirion’s SGP gas sensors are calibrated using ethanol since ethanol serves as a stable, reliable and economical proxy for TVOC. This is verified by linking the SGP sensor response to ethanol with the response to the ISO normed two kinds of …

Air quality sensors in Air Purifiers. How accurate are they?

· If there are high levels of, for example, formaldehyde, most sensors will not tell you unless designed for this specific measurement. TVOC sensors contain elements and are not designed to run continuously; they have to be switched off for intervals; otherwise, they lose accuracy and will give false readings, so TVOC readings are not continuous. They also have short service life intervals, usually a …
