Key Features

AQD series displays three most crucial parameters of IAQ; CO2 level, humidity and temperature. 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 series 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 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.

Note 1: In normal IAQ applications. Accuracy is defined after minimum 3 weeks of continuous operation with ABC. However, some industrial
applications do require maintenance.℃
Note 2: Accuracy is specified at room temperature +25°C and at normal pressure 101.3 kPa. Specification is referenced to certified calibration
mixtures. Uncertainty of calibration gas mixtures (+-1% currently) is to be added to the specified accuracy for absolute measurements.
