RESUN Salinity and Specific Gravity Meter
The RESUN Salinity and Specific Gravity Meter is a reliable swing-arm hydrometer designed for accurate water testing in marine and brackish aquariums. It provides full-range readings from 0 to 40 ppt salinity and 1.000 to 1.030 specific gravity, helping aquarists maintain optimal water conditions for fish, corals, and invertebrates.
Key Features:
- Easy-to-use swing-arm design with large, easy-to-read pointer
- Color-blocked “safe zone” for quick visual reference
- Stable wide base and “easy-dip” design to keep hands dry
- Temperature-corrected for 68°F to 85°F with ±0.001 accuracy
- Durable clear acrylic construction – lightweight and shatter-resistant
Usage Tips:
Before first use, fill the hydrometer with saltwater and let it sit for a few hours to “break it in.” Rinse thoroughly with clean freshwater after each use to maintain accuracy.
Applications:
Essential for saltwater aquariums, reef tanks, and brackish water systems where precise salinity control is critical for aquatic health.
