Fluval Sea Hydrometer provides an accurate and convenient method of measuring specific gravity and salt level in marine aquariums. Compact and easy to use, the hydrometer can be permanently installed inside the tank for continuous readings. Its slim, low-profile design camouflages well inside the tank and will not diminish the aesthetics of the aquarium. It can also be used as a portable device, allowing you to take samples simply by submerging it in the water. It features large, easy-to-read markings with ideal salinity range clearly marked in green for clarity.
The unique design of the Coralife Deep Six Hydrometer allows hobbyists to take water samples at six inches in depth without submerging their hands in the water, thus avoiding the possibility of contamination. Samples taken at six inches in depth have been proven to result in a more accurate salinity reading than surface samples.
Every unit is calibrated, tested and certified for accuracy. Each Deep Six Hydrometer is then assigned its own individual certification number.
Dimensions: 6.25" x 1" x 11"
