Review on AMTAST Detector Formaldehyde Temperature Multifunction by Jon Garcia

In general, this is the one I like the most. How accurate is that? Good question. Since I had a manufacturing facility, I added three more. Welding, plastics, solvent cleaning. filtered air treatment. Everyone. It has become a measurement tool for air system maintenance. Our show reported a (worst possible) score of 442 on a 2.5 scale. These units were set up outdoors at that point and measured within 15 points overall. It's pretty accurate. All I can say now is that it is a reliable tool and easy to use.
