With a lot of help from this forum I recently upgraded to full automation.
I am using the Pentair intellichem. firmware 1.030 rev B
I find that the ph reading is always about .7 lower than my measured samples. I have calibrated the probe and used the "tweak" feature but it is still off compared to my test kit.
Does it sound like a bad probe? or are there other tweaks any one can suggest. Thanks.
