So I've had some instability with the readings, but after installing the lab grade ph probe they sell for it, it's working much better. In the meantime I have a shipment on the way for a new reaction chamber which has an upgraded level sensor, float switch, and motor for the magnetic stirrer which are all supposed to really help with consistency and accuracy. As of now I still get some outliers around 30% of the time. The challenge now will be how to compensate...
Roberto, may need to revisit logging to a file and reading the results
