Aquarium Hydrometers & Salinity Tests

Aquarium Hydrometers - Salinity Meters, Specific Gravity Tests & More

Hydrometers play a crucial role in the maintenance of a healthy marine aquarium. These easy to install testers perform the essential duty of constant salinity tests, measuring your water's salt level to ensure that it remains at precisely the right spot for your pets' and plants' optimum health. Certain combination hydrometers also test your water's specific gravity, an important statistic related to the concentration of various microscopic materials in your aquarium water. Hydrometers perform these tests automatically and require no effort from you other than putting them in!

Pet Mountain's Aquarium Hydrometer store features top quality products from the most trusted names in aquarium equipment, maintenance and chemical balancing, including Instant Ocean, Oceanic, Coralife, Supreme, Hikari, Fluval and more. The Instant Ocean Hydrometer is accurate, reliable water test equipment that is absolutely vital to creating and sustaining a healthy, successful marine environment. Easy to read and simple to operate, the Instant Ocean Hydrometer delivers precise full-range salinity and specific gravity readings - accurate to 0.001 - and does it each time, every time. The Oceanic BioCube Mini Hydrometer monitors the salt level in your saltwater aquarium or sump, allowing you to easily maintain a healthy salinity. The Mini Hydrometer can remain completely submerged for constant monitoring. A suction cup allows for easy placement and secure attachment. 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.
