The purpose of the CO2 alarm is to remind you immediately so that you can take immediate measures to increase the CO2 concentration, such as opening or doors, or stopping the activities that cause the elevated readings. DM806 air quality detector is equipped with multiple advanced sensor chips, which is enough to achieve high- data processing technology. The CO2 accuracy value is ±50 ppm, and the PM2.5 accuracy is ±15 micrograms/cubic meter. Combined with the high-sensitivity sensor port on the side, the temperature and humidity measurements are more accurate and reliable, with an accuracy of ±0.54°F and ±3%.
