Monitoring Indoor Pollution;
Does anyone know if there is available in Hongkong a reasonable priced air quality particle counter for use indoors ? I only wish to monitor a single in room IQ150 to keep tabs on its performance. $HK 25,000 for a professional unit is a little expensive.
Is there such a thing like a carbon monoxide patch that changes colour as the pollution level varies or even something like the type of monitor that X-ray personnel are required to wear ? Any suggestions sincerely appreciated.
