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:
- Portable and waterproof
- Built with durable copper bodies
- Equipped with high-quality optical glass prisms
- Power-free and easy to operate in field conditions
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.
