2x Air Quality Detectors - BRAND NEW! - $15 each OR both for $25
I have two of these air quality detector units, brand new, still in their boxes. It was a case of buying online and accidentally ordering three when I only required one. I can say that the one that I am using works great. WHAT ARE THEY FOR..? It's very good for monitoring air quality, CO2 content in the air, temperature and humidity, and more! You can use at work, home office, car, or other applications to monitor air quality and temperature etc. Another great application is for call centre wor
