Instant Ocean Hydrometer

Regular price $12.99

Accurate, reliable water test equipment 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.

  • Use Instructions: 1. Rinse hydrometer with fresh water before using. 2. Slowly fill hydrometer by dipping bottom corner fill port below water surface until water flows up and over inner weir. 3. Dislodge air bubbles by tapping hydrometer, or pointer, gently with pencil. 4. Placing hydrometer on a level surface, read specific gravity (inside scale). For most marine aquariums, recommended specific gravity is 1.020 to 1.026. 5. Rinse hydrometer with fresh water before storing.
  • Care and Cleaning Instructions: Periodic cleaning is recommended to remove deposits that can accumulate on pointer, causing inaccurate reading. 1. Soak hydrometer in mild acid (vinegar) for 30 minutes, then rinse.
