Instant Ocean's durable, clear acrylic, swing-arm hydrometer is easy to use and easy to read. Full-range results in both salinity and specific gravity (0 to 40 ppt salinity and 1.000 to 1.030 specific gravity) with color-blocked "safe zone" to make routine testing quick and accurate. Features large swing-arm pointer, extra-wide stable base and "easy-dip" design to keep your hands dry while obtaining water sample. Temperature-corrected for use between 68° and 85°F with specific gravity readings accurate to ± 0.001.
Instructions:
Before use, condition hydrometer by soaking it in saltwater for 24 hours.
Step 1 - Slowly fill the Instant Ocean Hydrometer by dipping bottom corner fill port below water surface until water flows up and over inner weir.
Step 2 - Dislodge air bubbles by gently tapping hydrometer or pointer. Air bubbles on the pointer may result in inaccurate results.
Step 3 - Place the hydrometer on a level surface and read specific gravity (inside scale) and salinity (outside scale).
Care:
Rinse thoroughly in freshwater after each use to prevent mineral/salt buildup which can affect accuracy. Salt and calcium deposits that accumulate on the pointer will result in incorrect results. If crystallization occurs inside the unit, soak in lukewarm water or vinegar for 30-minutes, rinse with freshwater and air dry.
