Web Aquatics, Inc.

Unique intergrated hydrometer and thermometer. Provides accurate
measurement of specific gravity (degree of salinity) in a saltwater
aquarium. Patented design enables device to be permanently installed
inside aquarium, allowing time for micro bubbles to dissolve for
continuous, accurate, real-time reading of salinity in addition to
regular periodic reading. Built in digital thermometer ensures water
being tested is at correct temperature. Bubble-proof casing for easy
reading results

Continuous or periodic reading of specific gravity for saltwater aquariums

Accurate measurement of specific gravity
Easy to read digital thermometer
User friendly patented design
The most basic water quality parameter in a saltwater aquarium is the Salinity.
The unique, patented design of Red Sea’s hydrometer enables the hydrometer to be installed permanently inside the aquarium or sump giving a continuous “real-time” reading of S.G. in addition to being used as a regular hydrometer for periodic S.G. measurements. The Hydrometer includes a digital thermometer to ensure that the water being tested is at the correct temperature.
