Many hobbyist believe that the only way to calibrate refractometer is by using reverse osmosis/distilled water. That fact is usually true and is certainly appropriate for routine calibration, but it assumes that the refractometer was manufactured correctly and have not been damaged since manufacturing. As refractometers used by hobbyist become less and less expensive (with many now selling for less than $30), there is every reason to believe that they may no longer be accurate.
The only way to be sure that a refractometer gives correct information is to compare its accuracy against a pre-mixed saline solution. All refractometers should be checked in this fashion when purchased, and again any time there is a reason to be concerned.

Sinotech Hand Held Brix 0-18% Metalworking Fluid Refractometer P-rhb-18atc with ATC
Metal working liquid refractometer Industrial Fluid Testers are refractometers designed to provide a repid, accurate method ofr determining the ratio and concentration of water soluble, cutting fluids and other industrial lubricants. They are designed to assist machine operators in maintaining the delicate water/coolant balance. Proper coolant mistures reduce waste and tool worn while increasing feed and speed rates, improving the efficiency of your equipment. The industrial fluid testers' series are the right models of brix refractometers from model: RHB-5ATC, RHB-10ATC, RHB-18ATC, RHB-32ATC, RHB-50ATC. It's fully equipped with ATC that automatically adjust itself to correct temperature discrepancies during use.

Highly accurate and easy to read. The BioTek Marine Refractometer measures "true" seawater salinity levels, instead of just saltwater. This means that it measures usually unaccounted for elements such as calcium and magnesium as well as sodium chloride, giving highly accurate, precise results. Full ATC (auto temperature compensation) ranging from 5 to 30 degrees C. One scale checks the Salinity levels with the range of 0-100 ppt (with 1 ppt scale divisions) and the other scale gauges Specific Gravity with a range of 1.000 to 1.070 (+/- 0.001 accuracy).
