Ice cap salinity refractometer

I was looking in to getting one of these but that is concerning. Following along as accuracy is lore important then simplicity.

That's interesting... I wouldn't really want to press my luck when you're seeing it the same with 3 other testers.

On a similar note, the new SG calibration fluid "tropic eden" I got on the weekend is showing 37ppt where my older solution is showing 35ppt (old has NSW on the label if that means anything?). Not sure if I should ramp up to the new "35" or keep it where it's at, most stuff seems happy. I hate when there's conflicting results.
