refractometer calibration

[shyland83]

Does anyone have some sort of salinity calibration fluid that they could bring to the meeting on friday? I'm not very confident in my refractometer and don't want to pay 8 bucks shipping for a 3 dollar bottle of pinpoint calibration fluid. I'll gladly pay someone a dollar to let me use it.

I use RO water for mine. That's what the instructions say. I'm sure they'll sell you all kinda of stuff to do it too.

thats what i do too, but i've been reading that it's not always accurate
