It's basically new. It was bought and used one time by the old manager and he left it behind...that was two years ago and its time to get out of my warehouse! Mechanically its complete, the only thing its missing is an instruction manual that I assume would've came with it. Turns on and reads CO fine. Very simple to use, would be great for a building analyst for checking ambient co or even co in the flue gases.
i dont want this one bc I have two other flue gas analyzers that are more defined to what i do.
