Lazy saturday morning. Phone rings. " I saw your ad and have a Eco air meter I found in a house I bought. I dont know anything about it and have no idea if it works." I said, what do you want for it? He said, "I need some gas money" I said lets meet.
I bought it, cleaned the mice nest out of it. Plugged in the air hose and everything works !! Very solid, except for some rust on the back panel, on the bottom edge.
I think this one will stay just the way I bought it.
