FAQ
What pollutants does the Temtop monitor measure?+
The primary pollutants measured are PM2.5 and PM10, which represent fine particulate matter – often from dust, smoke, and vehicle emissions. It also tracks VOCs (volatile organic compounds) like formaldehyde and benzene, as well as temperature and humidity.
How accurate is the Temtop air quality monitor?+
Temtop monitors utilise laser sensors for PM2.5 and PM10 measurement, which are generally considered to be highly accurate compared to other consumer-grade devices. However, accuracy can vary depending on environmental conditions and sensor calibration.
Does the Temtop monitor require batteries?+
Yes, the Temtop air quality monitors run on three AAA batteries (not included). These provide around 18 months of operation under normal usage, but battery life will shorten with frequent data logging.
