Aecl AQD Series
4-in-1 Air Quality Display
CO2, PM2.5, Humidity and Temperature
(Model No.: AQD-101)

Made in Taiwan

AQD series displays four most crucial parameters of IAQ; CO2 level, PM2.5 concentration, humidity and temperature. It also provides date, day and time. It uses good quality sensors; such as the NDIR CO2 sensor, laser scattering principle sensor for PM2.5, temperature and humidity sensors which are usually available only in laboratory air quality diagnostic equipment. AQD-101 series measures CO2 and PM2.5 concentration which may not be noticeable by us and used the reading to control ventilation so that the indoor CO2 level can be kept below the recommended ASHRAE limit of 1000ppm and it can ensure better indoor air quality. Monitoring humidity is very important as extended period in an area with humidity over 60% or below 40% can create conditions for mold and mildew growth that may cause
allergies and affect general health.
