Apex does temp effect salinity reading

[Tsev03]

Just did an emergency move of livestock into 2 smaller tanks Does temp effect salinity reading? Tank overheated. Temp is 84 and salinity is saying 39. Is it really that high or does the temp cause a problem? Refractometer is reading 35 and I just calibrated it

I know when my tank goes up a few degrees, my salinity changes slightly in my reading, but not more than 0.2-0.3ppt

yes that is why they have an optional temp port on the salinity module.

And as I understand it per the BRS video, when you calibrate the salinity probe you're supposed to put the calibration solution pouch in your tank water to match temps. Assuming temps don't swing much I would think it'll be good with that.

When was the last time you calibrated the probes?

It’s been a few months. Temp is down now and the salinity is down to. As soon as I started taking the temp down it started lowering too. I’m glad I didn’t over react. Thank yall

The Apex doesn't quite measure salinity. It measures conductivity, which varies with temperature. The 53 you are looking for is 53 ms/cm or millisieverts per centimeter at 25 degrees C.

Don't take my word for it, here's @Randy Holmes-Farley's writeup.
