Hello,
If you want to calibrate it, you can use the correcting fluid which are orange liquid (pH4.01) and green liquid (pH7.0). To make the controller more accurate, it is better to calibrate with both pH4.01 and pH7.0.

Hello Amir! The liquid which we fill in the electrode cover are Reverese Osmosis water. You can fill with pure water or drinking water.
