VTT develops device for the simultaneous measurement of several gases reducing indoor air quality
VTT Technical Research Centre of Finland Ltd has developed a real-time and reliable device that can be used to measure ammonia and formaldehyde concentrations particularly in indoor air simultaneously, unlike with the meters currently in use. It is also suited to the measurement of emissions reducing outdoor air quality in city centres and traffic. "The device is capable of measuring the concentrations of several gases reliably and continuously with a sensitivity of less than 10 ppb, and it reports the results rapidly in just a couple of minutes or, if necessary, in seconds.
