Adjusting salt mixing for temperature variations

[slingfox]

Thank you for your time.

I have an old refractometer from Marine depot about 12 years old. That consistently reads 1.024 while my tropic marin hydrometer reads 1.026( which also is what my LFS gets) . I just couldn’t see carrying this hydrometer out side every time I needed to make salt no matter how good it is . It is so fragile I’m sure I would break it in about two or three days. Plus, as you can see from my first post I knew that the hydrometer reading would definitely be altered by abnormally cold temperatures. I just didn’t know that no adjustment would be necessary in the salt mix

Going to take sling foxes advice, and get the Vee Gee stx 3

Got another ICP test back from ATI this morning. My salinity came back spot on with the help of the VeeGee refractometer. I have not had to adjust calibration for over two years now:

I never said anything about using
40 degree water, I have central heat and even running water at my home lol Thanks for the tip
