$21.99 Refractometer for Battery, Anti-freeze, and DEF
Check out this $21.99 refractometer on Amazon. Lotta bang for the buck. Received it yesterday. Seems reasonably well-made and appears to work as advertised.

If I drew battery acid and placed it in the meter, and then washed it off, there is a 100 percent chance that I would have ruined clothing or worse.
You realize that a Refractometer takes ONE DROP on the glass? Any other device will have significantly more runoff than that. A simple faucet rinse eliminates all of it
Testing with a hydrometer does not require moving the acid from the battery port, but it may drip a bit upon removal. Using an eye dropper, acid may drip from the outside or inside till it gets to a meter. The eye dropper needs to be cleaned without any acid getting on anything. The meter needs to be held up to the eye with acid in place and cleaned without any acid getting on anything important.
Yes, I use a refractometer to check relatively safe coolant concentrations, but would never bring acid near my face.
