I have new bottle if you need some

roger i ordered some and for the meantime i did a cal. with r/o and a diy solution. Make your own calibration solution. 1 level tsp of Morton's Table Salt to 161mL of distilled water. This will give you 1.026 or 35 ppt. i just got the meter from marine depot. i feel secure with the results for now. but thanks for the offer i owe ya one.......

I tried making that DIY solution and I was waaay off from the pinpoint calibration fluid I just bought.
It's very difficult to get the measurements just right for something that exact and important.

I'll bring the bottle to the meeting Tuesday for anyone who wants to test their refractometers.
