Refractometer Calibration Fluid

[kelley_mc]

Anyone have any calibration fluid they can bring to the meeting? I have one of those famous blue refractometers that don't calibrate properly with RO/DI like the instructions say they should.

Thanks!

I use distilled, does that not work?

Nope... Supposedly, there is a problem with calibrating at a low range, like 0. It actually needs to be calibrated closer to NSW levels.
