Salinity meter on Profilux 3

Good day,

I am struggling to make a reading on my salinity probe. I am very technologically disadvantaged and need help. Bought the Profilex from someone that gave up the hobby. How do I get it working ?

Currently it is saying CO. S 1 0.9986. !

Also, where can I purchase an ph probe for the unit ?

Hello,

have a look at our GHL Store, where you can also get the probes as replacement part:
