Temperature and Salinity relationship...

[Randy Holmes-Farley Verified Community Expert]

Can you recommend a refractometer?

I prefer salinity measurement by conductivity, but if you use a refractometer, just calibrate it with a 35 ppt standard, not di water.

Just to graphically see the effects or correlation of temperature on "salinity" on a conductivity probe, in this case, the Apex conductivity probe...

I think you must either have temperature correction turned off, or the apex is using the wrong correction factor. The salinity is not changing as it shows.
