Portable Salinity Refractometer LPSR-A12 measures 0 to 28% with ±0.2% accuracy for precise concentration determination. The temperature compensation range of 10 to 80°C allows it to perform consistently in changing environmental conditions. It requires only 0.2 mL of sample for testing, making it efficient for small sample analysis. The shading cover design improves repeatability and stability, even under strong light. Ideal for rapid and accurate solution concentration analysis in laboratory and field applications.

Our Portable Salinity Refractometer LPSR-A12 is designed for rapid, precise refractive index measurements. It is ideal for quality control in industries like food and beverage, pharmaceuticals, and chemical manufacturing.
Labtron Portable Refractometer comes with a wide range of models to measure the boiling and freezing points, brix, TDS, density, specific gravity, refractive index, and concentration, of fruits, beverages, oils, and organic solvents. They obtain precise measurements with automatic and zero calibration using distilled or tap water. Some models are equipped with standardized brix scales for easy reading and accuracy. To conserve battery life, they automatically power down after one minute of inactivity. Our microprocessor-controlled Portable Refractometer provides easy-to-read results on an LCD screen.
