Calibrating Apex salinity probe or adjusting readings?

[mike550]

Okay. Total newbie mistake. I tried to calibrate my salinity probe, and didn’t quite understand the process. After some frustration I gave up trying to calibrate the probe and threw out the calibration solution.

Here’s my question. Is there a way to manually adjust the salinity reading on the probe? I use a Hanna checker for salinity and have confidence in the measurements. Is there a way to adjust the Apex probe to match the Hanna or do I need to buy a new calibration packet and try again?

Thanks. I was hoping to do it without buying calibration package. But your link was super helpful on how to calibrate this properly.
