At Fuzhou Lindian Technology, we offer reliable and easy-to-use handheld salinity refractometers designed specifically for the needs of the aquaculture industry. Accurate salinity monitoring is critical for maintaining a healthy aquatic environment, and our instruments provide quick, precise readings to support fish farming, shrimp hatcheries, and marine research.
Our refractometers help aquaculture professionals:
Monitor Water Salinity – Ensure optimal salt levels in ponds, tanks, or open-water systems for species such as fish, shrimp, crabs, and mollusks.
Balance Freshwater and Seawater – Fine-tune salinity levels to match the tolerance and growth requirements of different aquatic species.
Improve Survival Rates and Growth – Stable salinity improves immunity, feeding efficiency, and overall stock health.
We offer a wide range of models with different salinity scales, suitable for both low-salinity and high-salinity environments. All units are:
Whether you manage a commercial fish farm, a hatchery, or conduct marine biology research, our refractometers provide the accuracy and durability you can count on.
| Categories | Suitable Samples | Measurement sample range | Materials | Model |
| Salinity | Low-salt pickled vegetables, mild-tasting sauces, soups, seasoning sauces, and other liquid foods with low salt content | Salinity 0-100‰ Salt density 1.000-1.070 g/mL |
Using solid copper for key parts like the prism base and eyepiece | RHS-10A |
| Medium to high-salt cured meats, high-salt sauces, brine from salted foods such as pickles and preserved vegetables | Salinity 0-28% | RHS-28A | ||
| Seasoning sauces, marinated products, compound flavored beverages, salt solutions for processing, salted seafood, grapes, persimmons, lychees, fruit juices, low-sugar sodas | Brix 0-32% Salinity 0-28% |
RHBS-28A | ||
| Summary of Recommendations: For measuring low-salt products, choose RHS-10A. For measuring medium-high salt products, choose RHS-28A. For products that need to measure both sugar and salt, choose RHBS-28A. |
