I use this probe to monitor my water that is being treated. The treatment increases the ORP from about 200 mV to 550 mV. The recording works much better than with the previous model and there are less fluctuations.
However, if I now put the probe into a new sample (ORP = 200 mV) it takes a very long time (> 1 hour) for the displayed value to drop from the 550 mV to the 200 mV. I use your Arduino code, a Arduino Mega 2560 and a Gravity: Analog Signal Isolator. Restarting the Arudino does not help either.
Why does it take so long? Can you help me please?
Thank you very much.
I've read that the expected lifetime of the probe is one year. Would this depend on how often it's used? I intend to use this in to measure ORP in fermenting grapes, where it would be used 24/7 a maximum of 20 days out of the year. Should I still expect it to last for one year?
JaneYu Hello, this will greatly increase the life of the probe if your frequency of use is not very high.
I got the probe and using the sample sketch to get measure the orp values. I always get negative potential. Is there something wrong with the probe?
