reefin link said:The unit came with the calibration solution so all good there! I was looking at the digital Milwaukee refractometer on youtube just lastnight! I think if I got one for a gift it would be fine but I don't think I'll buy one. Unless I was running a store with several setups then it would be handy!

Is there a problem just using RO/DI water? Assuming 0 TDS

Darryl_V link said:Good question. I've had my refractometer for years and only every calibrate with 0tds water. I did once buy calibration fluid but it worked out the same for me so I just went back to using RO/DI water.
