The Ammonite shaped hydrometer from AquaticLife™ integrates a scale for accurate measurement of salinity in a reef or marine aquarium. The yellow needle above the blue background provides easy observation for the beginner or advanced marine hobbyist. It uses a patented water-fill design which allows the water to enter from the bottom of the unit, thus reducing the amount of bubbles that can stick to the measuring needle. This design produces an accurate salinity reading in a very functional and aesthetic package.
* Hydrometer Ranges:
* 16 to 43 ppt
* 1.012 to 1.032 specific gravity
