Optical Salinity Meter

The optical salinity meter calculates salt concentration by measuring the change in the optical refractive index caused by dissolved salts in water. It uses a prism and a light sensor to detect the degree of light deflection and directly displays the salinity value. It is suitable for rapid on-site testing in fields such as marine aquaculture, water quality monitoring, and food processing.
Selection
When selecting, consider whether the measurement range and accuracy match the sample salinity. Pay attention to the automatic temperature compensation function to adapt to different environments. Check whether the instrument's protection rating meets the moisture-proof requirements of the usage scenario. Confirm whether the calibration method and data output functions align with operational habits.
