CO,CO₂,light and sound

Everyone is exposed to different environmental influences in their day-to-day lives, for example at the workplace: illuminance, sound level and indoor air quality are all significant factors which influence people's performance and their well-being. Testo offers suitable measuring instruments for controlling each of the measurement parameters of lux, sound and CO2 (for indoor air quality).
