AQD-100 displays three most crucial parameters of IAQ; CO2 level, humidity and temperature. Easy installation and the recommended height of installation is 2~3M above the floor level. It also provides date, day and time. It uses good quality sensors; such as the NDIR CO2 sensor, temperature and humidity sensors which are usually available only in laboratory air quality diagnostic equipment. AQD-100 measures CO2 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. Monitoring humidity is also 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.
