What is refractometer calibration fluid?
Refractometer calibration solution is used to accurately calibrate your refractometer for testing natural sea water or synthetic sea water.
How is a refractometer calibrated?
To calibrate the refractometer, do the following: Make sure the calibration fluid* and the refractometer are at the same temperature. Open the cover and put a drop of calibration fluid onto the prism. Adjust the calibration screw on top of the refractometer until the brix value reads 70.
Which solution is used to calibrate a refractometer?
AG Fluids are aqueous solutions that cover the range 1.33-1.40 RI (0-40 °Brix equivalent) and have a shelf life of 12-months. They are ideal for calibrating refractometers that have temperature control in both food and industrial applications as well as instruments that have AG Fluid temperature compensation.
How do you calibrate salinity fluid?
Use 3.65 weight percent sodium chloride solution to match 35 ppt (sg = 1.0264). It can be made by dissolving 3.65 grams of sodium chloride in 96.35 grams (mL) of purified freshwater. 4. Dissolve the total salt (79.3 g) in the total water volume (2104 g) to make an approximately 3.65 weight percent solution of NaCl.
Can I calibrate my refractometer with tap water?
Can I use tap water for the calibration of my refractometer? It recommends distilled water. Will this make a difference? No you can not.
