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.
Features Conductivity: 53.0 mS
Salinity: 1.0264 SG / 35 PPT
Refractive Index: 1.3394 at 25Â°C

Instruction: Hold the product in an up right position and slowly submerge it into water when the water reach the water line indicated,please take out the hydrometer and place it horizontally for read the number. The right side will be the salinity (PPT) and the left side is the specific density. Please take out water from the outlet and swill the meter use fresh water. Please make sure no bubble attached on the pointer.
