This is some test equipment that was left with me and has been on the shelf for almost 10yrs. I was all working and was certified when I got it. I am posting pictures but can only post four. Please contact me for more information and pictures. I believe that I still have the sampling pump, it is not shown but upon interest I will verify. Thank you Location: delta/fairbanks it's NOT ok to contact this poster with services or other commercial interests alaska
