Keep your aquatic systems stable, healthy, and optimized for growth.
Follow this guide to choose the right refractometer
Refractometer Use Cases in Aquaculture
Fish Farms, aquariums and researchers use our refractometers to:
Monitor Water Salinity
Ensure optimal salinity conditions in seawater tanks, hatcheries, and ponds to support healthy fish and shrimp growth.
Support Water Quality Management
Quickly check seawater or brackish water conditions to prevent stress and disease in aquatic species.
Product Selection Guide
Use this guide to select the right refractometer model based on salinity range and the fish or aquaculture species you are farming.
For most aquaculture species, the RHS-10A model provides sufficient range and higher low-end precision, while the RHS-28A model is recommended for broader seawater monitoring, specialized high-salinity systems, and scientific or research applications requiring wider measurement coverage.
| Species | Approximate Salinity | Suitable Model | Measurement Range |
|
Brackish Water Species Tilapia Catfish Freshwater Prawn Eel Mud Crab |
~0–1.5% salinity | RHS-10A |
Salinity 0-100‰ Salt density 1.000-1.070 g/mL |
|
Brackish-Transition Species Milkfish Grey Mullet Whiteleg Shrimp Oyster Clams |
~1.0–2.5% salinity | ||
|
Marine Species Snapper Sea Cucumber Abalone Tiger Shrimp |
~2.5–3.5% salinity | ||
|
Special Aquaculture Brine Shrimp Halophilic Microalgae/Bacteria |
