Air Quality CO2 meter
535 Air Quality CO2 measurement
Testo 535, the ideal CO2 measuring instrument for building engineers.
Bad air quality in enclosed rooms which is caused by a too high CO2 concentration (> 1000 ppm) can lead
to tiredness
lack of concentration and even to illness (sick building syndrome SBS.)
