Dual-Scale, Easy Readout: Inner scale shows specific gravity (SG); outer scale shows salinity (ppt). Big window and clear markings let you read values at a glance for mixing new saltwater or daily checks.
Bubble-Resistant Filling: Submerge and fill about 15 cm/6 in below the water surface to avoid surface film and trapped air. The built-in baffle reduces bubbles; gently tap to release any that cling to the pointer for a truer reading.
Set-Down Accuracy: After filling to the safety line, remove and place the hydrometer on a level surface to stabilize the swing-arm and get a consistent result.
Saltwater-Safe & Versatile: Durable, reef-safe plastic body for marine and brackish tanks—great for fish-only, reef, quarantine, seafood pools, and water-mixing bins.
Easy Care, Long Use: Rinse with fresh water after each test. If salt crystals form, soak in warm water or diluted vinegar for ~30 min, then rinse and air-dry to keep readings consistent.
