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.

Scale does not match advertising

A.N.I.T. · August 24, 2024

The scale of this refractometer shows brix% and not antifreeze concentration like what is advertised. One star for false advertising.

Not as advertised

D.L. · September 4, 2024

Did not include Glycol readings on the visible scale. Useless.
