They measure the concentration of carbon dioxide, which people exhale when they breathe, along with other things like, potentially, virus particles. The more well-ventilated a space, the lower the reading on the monitor screen — meaning not only less carbon dioxide but also less of the stuff like Covid that might make people sick.Additional Parts: (4) M4x12 Flathead Screws(4) M4 Nuts(2) .9" shank diameter nails (head trimmed off to a length of 1.5")(1) 1" Velcro Strap of some kind.
