I just purchased a new refractometer and wanted to know about calibrating it. I'm sure I need to calibrate this before using it. It does have Automatic Temperature Correction but I need to know how to calibrate it. I know you can buy a saline calibration solution but is there anything else I can use to calibrate it? Can I use something like distilled water?
