CO,CO₂,light and sound

Everyone is exposed to different environments indoors/outdoors in their everyday lives. For example, in an average workplace illuminance, sound level, and indoor air quality are all significant factors that influence people's performance and well-being. Testo offers suitable measuring instruments for controlling each of the measurement parameters of lux, sound, CO and CO2 (for indoor air quality).
