Monitoring air quality

From: Cihat Uzun <*objectconservation<-at-*> Date: Tuesday, April 20, 2010 · objectconservation<-at-

Are there any devices for measuring air particles (dust) and
gaseous pollutant (formaldehyde, acetaldehyde, formic acid, and
acetic acid) that you can recommend? Our preference is a device that
monitors materials as many as possible. It must be easy to use.
