How often do Apex Salinity Probes need calibration

[Jyetman]

Noticed mine is off a bit is this normal after several months? How often should they be recalibrated? Can I just adjust the temp compensation to fine tune it?

What is a bit off?? What is your salinity as measured with a properly calibrated refractometer and what is your Apex reading? I don't calibrate very often. Maybe once every several months but as I have mentioned on many occasions, Conductivity readings are more for trends than determining your actual salinity.

It may just be my OCD talking I adjusted the temp comp by .1 and its now back where I want it.

I never got mine to read right. I know apex said that other probes and wires could cause it to read off
