Indoor Air Quality

Temperature, humidity, Airflow, CO and CO2 are the main parameters most often measured to assess indoor air quality. Poor air quality in offices, homes, schools and institutions can lead to excessive fatigue and poor concentration. 

The testo 535 is an efficient CO2 instrument for assessing indoor air quality while the testo 317 and testo 315 gas leak detectors check the CO level in ambient air. Testo sound level and light meters are extremely sensitive instruments that provide reliable and immediate feedback in ranges beyond the human ear and eye.
