I have been relying on ph value from Alkatronic. For fun I bought a standalone wilwaukee ph monitor mc120. Calibrated both Milwaukee and Alkatronic just now. Both are within 0.01 before adjustment/calibration.
Run test on both :
Milwaukee - 8.6
Alkatronic - 8.1
Kalk at 8dkh
Both numbers are fine. The real ph is probably somewhere in the middle .
Any idea what causes the difference?
