Salinity Determination RefractoMeter

The refractometric salinity meter operates based on the principle of changes in the refractive index of light in solutions of varying concentrations, converting the measured critical angle into salinity values. It is used to detect the salt concentration in seawater, brine, and industrial solutions, providing direct readings in applications such as aquaculture, food processing, and environmental monitoring.
Selection
When selecting, consider whether the measurement range and accuracy match the sample salinity, and pay attention to the temperature compensation function and calibration method. Choose a handheld or benchtop model based on the usage scenario, check the material's corrosion resistance, and ensure ease of operation and clarity of data reading.
