Contact: Hello
Agent: Hello
Contact: I have a question.
Agent: Yes
Contact: I have a Zodiac salt system that is now one year old. I have calibrated the pH and REDOX probes, but the value does not match the photometer. What could be the cause?
Agent: What is the difference in value?
Contact: The photometer shows pH 7.33 and on the system, the pH value is 6.1.
Agent: When you dip the probe into the standard solution, do you measure the value of the standard?
Contact: Yes, when I dip it into the 7.01 solution, it shows 7, and with the 4.1 solution, the value is 4.
Contact: I have calibrated the probe three times now, but the value still does not match the photometer.
Agent: When you put the pH probe into the pH 4 standard solution, what value do you read? 4? No calibration mode!
Contact: When I put the probe into the pH 4 solution, it shows me the value 4.
Agent: The standard solutions are the only reference. If your solutions are correct, what does the photometer measure in pH 4 and pH 7?
Contact: When I put the pH probe into the buffer solution 4, it shows me the value 4, and when I put the probe into the buffer solution 7, it shows me the value 7.
Agent: And the photometer?
Contact: When I then reinstall the probe, it shows the value (when the filter pump is running) 6.1, but the photometer shows the value 7.33.
Agent: When you measure the standard solution with the photometer, what does it give you?
Contact: ??
Agent: Sorry
Contact: 4 and 7
Agent: Do this, place the probe in a glass of water, let the system run, and see if the value moves.
Contact: Do you have any other possible causes?
Contact: Yes, the value moves until it reaches the target.
Agent: No, I don't understand, everything seems to be working fine, let the system run, maybe the water needs to mix.
Contact: Okay, it's no use.
Contact: I will try to calibrate it again in 2 days.
Agent: Yes
Contact: Thank you
Agent: You're welcome
