At this point I’m pretty well convinced that my unit is reading way low. This morning I remembered that I had some Neptune 53 ms solution that was not old and was still sealed in a single use foil pouch. I tested the icecap probe with that and got a reading of 31.9 ppt. 53ms should be 35 ppt.
I’m going to return the icecap probe and stick with the Milwaukee digital refractometer.
