Hello I am Torben from Germany and have a few problems. First connection from smartphones to Alkatronic brake after few minutes so I have problems to calibrate pump A. I test I by Samsung Galaxy S7 and S9+.
Next Problem is that I have pH sulution 7 and 9. How I can change 4 to 7 and 7 to 9. For an other pH elektrode I have only this. Why you put not the right sulution, such a low price article, to this expensive produkt so everybody can start directly?
