The measurement scale at left is not labled - is it supposed to be showing g/ml of specific gravity? If so, the top 3 & bottom 3 numbers are wrong.

The picture of this scale is not an enlarged view in proportion. This is a schematic. Thank you for your curiosity and seriousness. But you can't use this diagram to measure any battery fluid.

Is it suitable for testing glycol?

Yes. It is used to test glycol concentration and freezing point temperature. It is also used for other liquid tests.

Will this come with a box or a bag? Description says bag, but reviews say box...

I got a box with is and I believe a bag the refractometer sat in in the box. I gave mine to my old helper and ended up buying one at Fw Webb

How does it know the difference between glycol or DEF or battery water?

Not sure. Sometimes you just have to hit the I believe button.
