Do you have some problem with the salinity probe?
Can I change the salinity for density? (example: 1.025)

Thanks

Salinity varies with temperature. If you assume temperature is constant, you can mathematically convert one to another.

Can I do a code to have this alternative?

Yes, you can code.
Please post back your code so others can use it too :)

Isn't the compensation part already done?

Wouldn't it just be a matter of mapping the values now?

Even though the compensation is there, it hasn't been much used to confirm that it really does its job.
But yeah, you can assume it would be compensated or constant and then map values.

i have been using it in a cup of water for testing. i think i had it calibrated a little high but it has appeared to work. I need to hook it up to my tank and watch it for certain though. hopefully i can get it connected tomorrow and see how it works.
