Tips: How accurate are air quality monitor sensors?

Different models of air quality monitor sensors vary in accuracy, usually domestic air quality sensors are suitable for daily monitoring of environmental quality, while industrial air quality sensors are more accurate and suitable for specialised situations such as laboratories or environmental testing stations. When in use, you should calibrate the device regularly and follow the maintenance advice provided by the manufacturer to ensure the accuracy of the test results. And, air quality monitoring sensors require regular maintenance to ensure accuracy. Maintenance typically includes cleaning the sensor surface, replacing or cleaning the filter, and calibrating the device for a specific period of time.
