Glass Floating Hydrometer with Built‑in Thermometer

• 2‑IN‑1 FLOATING SALTWATER TESTER: This glass hydrometer combines specific‑gravity salinity testing and built‑in water thermometer. Measurement range: SG 1.000‑1.060, temperature 0‑40℃ with dual ℃/℉ scale. Simply float it in saltwater to get stable readings, ideal for home reef tanks, marine aquariums and commercial seawater aquaculture. Designed for salt‑water use.
• MULTIPLE REFERENCE RANGE MARKINGS: Transparent glass body with clear printed markings. General seawater aquaculture:1.020‑1.030; Reef‑coral tanks:1.020‑1.025; Seafood holding tank suggested:1.020‑1.023. Read salinity density directly to help maintain stable tank water parameters.
• WIDE SALT‑WATER COMPATIBILITY: Works for reef tanks with SPS/LPS corals, marine fish‑only tanks, shrimp systems and seafood holding tanks. Suitable for beginner hobbyists as well as commercial seawater farming monitoring.
• FRAGILE GLASS CONSTRUCTION REMINDER: Built with glass shell and internal ballast at bottom. Handle gently, avoid dropping or heavy impact. Please inspect the item right after delivery for shipping‑caused breakage. Lower slowly into water instead of dropping.
• PRACTICAL 8.27 INCH FLOATING DESIGN & READING NOTE: Total length 8.27 inch, lightweight floating structure. Can be placed inside display tank, sump or saltwater storage tank for daily salinity and temperature checking. Note: Readings are influenced by water temperature. For maximum precision, verify with a refractometer.
