Calibrate Refractometer

[cirujano]

I bought a Pinpoint calibration fluid to calibrate my Refractometer, but I have no clue how to do it. Right now, its reading 1.030. Any idea how to adjust it?

On the top of it there should be a little cap that you take off and then use a small screw driver to adjust it.

You need to buy the calibration solution or you can just make your own like Randy's : http://www.reefkeeping.com/issues/2004-06/rhf/index.php
