Refractometers are commonly used to measure sea water and control the salinity of water from fisheries and fish farms, natural sea water for aquariums, artificial sea water, and the salt water used for fish storage.

The salinity in parts per thousand (ppt) of seawater can be measured with only a small quantity of sample and with a simple procedure. The temperature is automatically corrected,, so that it is not necessary to worry about the temperature of samples. The MA887 is used in the aquaculture industry to measure the salinity in parts per thousand (ppt) of seawater or artificial seawater.

Measuring Method

Salinity in Seawater can be measured with MA887 Digital Refractometer described here.

The MA887 is an optical instrument that employs the measurement of the refractive index to determine the salinity of natural and artificial seawater, ocean water or brackish intermediates.
