Abstract
An immersion-type on-line refractometer useful for the in-situ measurement of salinity and temperature of sea water is developed, and its performance is examined by applying the refractometer to known salt solution having salt concentration between 2 and 4 % similar to practical sea water salinity. Since refractive index and temperature are measured simultaneously, it is possible to compensate the effect of temperature for fast and direct measurement. The outcome of salinity measurement for the different concentrations of salt solution indicates that the device is suitable for the salinity measurement by yielding stable and reproducible reading.
