Fluval SEA Hydrometer
The Fluval Sea Hydrometer provides an accurate and convenient method of measuring specific gravity and salt levels in marine aquariums.
Compact and easy to use, the Fluval hydrometer can be permanently installed inside the tank for continuous readings thanks to its strong suction cup.
The slim, low-profile design of the Fluval Sea Hydrometer 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.
- Measures specific gravity and salt level in aquariums
- Accurate & easy to read
- Can be used in or out of the aquarium
