Refractometer Solution

Steps to calibrate your unit:

1) Using the dropper place a few drops of the solution on the glass and close the lid.

2) Looking through the unit and turn the screw until the unit reads sg 1.026 (35ppt)

3) Screw the cap back on your calibration solution for storage. It is important that the cap is on tight or water will evaporate and ruin the solution.

*** Do not calibrate using RO/DI water as this will not give accurate readings***
