[RE-wrenches] NON Digital Hydrometer

[Shasta Daiku]

Hmm….Are they really safer? 

1) Put rubber gloves on and remove battery caps. The chance of getting electrolyte on the gloves 
    pretty high, especially after checking a couple dozen cells.
2) Extract electrolyte with pipet. Dribbles here and there
3) Place drop on Refractometer. More Dribbles possible.
4) Hold refractometer like a spyglass up to an eye for viewing, hopefully wearing eye protection
5) Wipe and repeat. Again possible many times.

I just can’t get over the idea of willingly placing things that may have acid on them near my face.

I recently consulted on a DIY/Wholesale Solar project and discovered that they ship a complimentary Refractometer with their battery banks. I was shocked and considered asking the group here for opinions.

AND the darn thing will not break unless you drop it on the floor unlike how many glass hydrometers over the years. I would have to add easier to teach the clients who are interested in self battery service too.
