Hi,
the Ph reading on the proflux has been reading 9.5 ph, wenn a connect a tunze 6101, wenn a disconnect the tunze form the 230v the reading is 8ph,
also if a unplug the din plug so the pump end up at full power the ph starts to return to normal.

The signal of the pH sensor is very slight.
Maybe the tunze generate too much electromagnetic noise - and interferes the signal of the pH sensor.
Try to sepearte both as much as possible - they should not be too close together.
The ph probe is in the sump, i have the power suply from the tunze also connected to a diferent 230v outlet, the ph is then also to high.
the jump in ph is only when a make a electrical connection white the pomp.
do jou have a 0-10v liniare optocoupler interface to connect the profilux to the tunze, so it is electrical isolatet.
sorry for my spelling
Ruud
the same thing is happening with my radox sensor, 4 tunze 6105s connected to the profilux the reading is 85-150 when the tunze is not connected reading all ok 320.
