Salinity Refractometer has scales in the range of 0 - 28% with ±0.2% accuracy. Designed to measure salt & brine solutions for testing the concentration of prepared food solution, used mainly in the food industry. Scale enables direct determination of salinity in water that contains dissolved salt & little or no other dissolved solids. Uses the refractive index to determine sodium chloride concentration; analysis is simple & fast, requires few sample drops & takes about 1.5 sec per test which makes taking many measurements easy for an operator. With this refractometer, you can: * Manage best food preservation process for long shelf life* Know the Salt Concentration in a Brine Solution for Curing Salmon, etc.* Test concentration of prepared food solution, used mainly in the food industry like seafood curing food, pickles, soup, cooked food, fish processing products, seawater, brine, etc. Just a few drops on the testing prism, cover, look and read the result!
