I ran across this while looking at other battery charging related stuff. Kind of interesting. Relatively small compared to the glass tube versions, about the same size as an EZ-Red. All plastic, no corrosion or, hopfully, breakage if you bring it along with you. Supposedly bubble free fill, which would make life a lot easier. Then there is the big plus, automatic temperature correction, and high accuracy.
Anybody ever seen, or heard about these? I am looking for something easy to carry with us, that cleans up and stores easily to keep the acid away from everything else.
