Boxtech Aquarium Marine Test Hydrometer for Fresh Water and Sea Water

Product Review (submitted on December 3, 2021):

I own a refractometer which is extremely accurate but I still like the convenience of just dipping a box type specific gravity meter and getting instant results.


This Boxtech one has been very accurate so far and almost matches what my Refactometer says. It reminds me of the very first hydrometer I had 30+ years ago in its design and accuracy.
