We just purchased a MISCO digital salometer for measuring sodium chloride concentration. We have a process that needs to mix DI water with Sodium Chloride (NaCl) to 100% saturation. I am hoping that the meter I have bought is the correct version for this job?
The MISCO Digital Salometer is a refractometer that measures the percent saturation of sodium chloride (NaCl) salt in water. The refractometer will display the percent saturation of sodium chloride from 0 to 100% as well as display the freeze point of the solution in either Fahrenheit or Celsius (model dependent). A digital Salometer overcomes many of the problems associated with traditional analog Salometers. Traditional Salometers are cumbersome to use and time consuming. They are simply a glass or plastic hydrometer with a special scale that displays degrees SAL instead of specific gravity. In use, the traditional Salometer is floated in a graduated cylinder containing salt brine. The reading is taken at the point at which the surface of the fluid crosses the analog scale divisions; the temperature must then be read with a thermometer, followed by a manual temperature correction of the reading.
There is no method for field calibrating the apparatus; it is difficult to resolve the tiny scale divisions; it must be thoroughly cleaned and dried to prevent salt residue from influencing subsequent readings; and it is easily broken. The MISCO Digital Salometer is much easier to use and much more accurate. Simply place a couple of drops of sodium chloride solution on the measuring surface, close the evaporation cover, and press the button to initiate the readings. The percent saturation is displayed nearly instantly on the large LCD display.
