Airscan diagnosis devices were developed for a professional inspection of indoor air quality conditions. The device is capable of measuring the most common indoor air pollutants, especially focusing on toxic pollutants like formaldehyde. In combination with IoT sensors, artificial intelligence allows data collection, generate technical reports, and develop visual infographics. Diagnosis devices are designed for indoor air quality inspections and can be used for ASHRAE, WELL, BREEAM and Leed certification processes.
