IAQ Monitors FAQ | Sauermann group

There are two TVOC sensors available – the low range is 0 to 20,000 ppb (20 ppm) and the high range is 0 to 200 ppm. When measuring VOCs, you must choose a low or high range TVOC sensor (not both). Since Formaldehyde is a VOC, why would need I need a separate sensor for this gas?
