Testing Battery Acid
It’s used for testing battery acid. Worked great.

Works.
This worked really really well. The first time I used it, but it is extremely fragile. You have to pee careful because I broke it. Just trying to clean it out, but it works. Excellent it did its job. You just have to be extremely delicate with it. I used it for my forklift battery.

Works well but I would prefer a longer tube for inserting into the battery
Works but would be better if it had a longer tube for inserting into the battery. My battery bank has large flooded lead acid batteries and a longer tube would make it easier to use.
