There is a tolerance of +/- one so should be good

So whats my salinity technically? 1.026 OR 1.027 or no way to know?

I target 1.025 but 1.026 acceptable

It is technically a wider range than that. It’s claimed specs are not very tight.

But even if it was accurate to the nearest 0.0000001 units, if the actual values were 1.0265000000, it would bounce back and forth.

A true 1.026 could read anything from 1.024 to 1.028

I think you might be overthinking it. You should be all good to go knowing the Accuracy range.

Im overthinking it a little. But it just kills me not know my exact salinity.

You want an Apex with a conductivity / salinity probe. Then you wouldn't have a clue what your salinity was.

Sorry. I have one and I'm less than impressed with it, that's all. Perhaps I shouldn't have made that post.

IMO, it’s important for people considering devices to see more than the marketing advertisements for them.
