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.

Je fais du Kombucha et je voulais savoir si il y avait beaucoup de sucre. Après avoir testé avec des boissons zéro sucres et boissons très sucrées, j'ai pu vérifier que ça fonctionne très bien. Et ça vient avec un petit tournevis pour régler la lecture et une pipette pour extraire et déposer le liquide sur la plaque de lecture. Excellent produit.

This refractometer is awesome. Used some samples to test the calibration and it was perfect out of the box. Helped me determine the mixture in my vehicle.
