Choose the right probe for an electromagnetic pH controller FPH.

Client :
Which probe should I change on an electromagnetic pH regulator "FPH"? The device always pumps with a reading always at 100%, I think it's the probe? Thank you for your response.

Technical Advisor :
Hello, Yes it might be the probe! Are you reading the pH value on your device?

Client :
Yes, it is at the maximum setting.

Technical Advisor :
Are you in pH minus?

Client :
Yes.

Technical Advisor :
Put the probe in water with vinegar. If the probe works, then the pump should stop. Can you take a picture of your probe and your regulator? I will check the probe you need.

Client :
Okay, I will do the test. If it's the probe, what reference is needed for this model that is a few years old?
