Description
Uncompromising Salinity Accuracy for Sensitive Reef Systems Maintaining a precise salinity level is critical for coral health, invertebrate survival, and overall reef stability. While swing-arm hydrometers and uncalibrated refractometers can drift over time, the Tropic Marin High Precision Hydrometer Set offers lab-grade, physical measurement reliability that never loses calibration. Handmade in Germany, this glass hydrometer allows aquarists to measure specific gravity with extreme precision. Paired with a high-quality 500 mL graduated cylinder, testing outside your display tank is clean, easy, and accurate. Key Features & Benefits Lab-Grade Precision: Maximum deviation of less than 0.0002 at 77°F (25°C), ensuring exact salinity tracking for delicate stony corals (SPS/LPS). Included 500 mL Graduated Cylinder: High-clarity testing vessel with a stable, removable plastic hexagonal base and pour spout. Prevents messy spills and protects the floating hydrometer from tank currents. Large, Easy-to-Read Scale: Features a fine, expanded scale marked in increments of 0.0005, making it effortless to pinpoint exact readings between 1.020 and 1.032. Recommended Target Indicator: Features a highlighted recommended range on the internal float for quick, at-a-glance checks. Handmade in Germany: Crafted to strict standards using high-grade glass to maintain consistency and long-term durability.

Resolution / Graduations 0.0005 Maximum Deviation ±0.0002 Reference Temperature 77°F / 25°C Cylinder Capacity 500 mL Cylinder Construction Borosilicate glass with plastic base & bumper ring Hydrometer Length ~14 in (35.5 cm) What’s Included in the Box (1) Tropic Marin High Precision Glass Hydrometer (1) 500 mL Glass Graduated Cylinder (1) Removable Hexagonal Plastic Base (1) Protective Plastic Cylinder Bumper Ring How to Use Fill the included 500 mL glass cylinder with aquarium water up to approximately 3/4 full. Ensure the sample temperature is as close to 77°F (25°C) as possible for optimal accuracy. Gently lower the clean, dry hydrometer into the cylinder, giving it a light spin to dislodge any clinging air bubbles. Read the specific gravity scale directly at eye level at the bottom of the liquid meniscus.
