Etatron pH probe replacement: Consultation and solutions for technical issues.

Customer:
Hello! I have an Etatron system and I need a new pH probe.

Technical Advisor:
Hello. One moment please.

Technical Advisor:
Here is the pH probe for Etatron.

Customer:
Does it fit on a system "CXB4000301"?

Technical Advisor:
Yes, it fits.

Customer:
OK, thank you! Is it a REDOX probe or a "normal" one?

Technical Advisor:
Do you want a pH probe or a Redox probe?

Customer:
If I knew.... 😉 I want to replace my current probe, how can I determine which type I have?

Technical Advisor:
What do you read on your device?

Customer:
Sorry, what do you mean?

Technical Advisor:
You read numbers like 7, 6 or 650, 700.

Customer:
Oh, I see.... On my device, I read the pH value. I wanted to calibrate the probe, but in the pH 7 solution, it never reaches a value below 8.9. So I think the probe is broken.

Technical Advisor:
In that case, it's good. Here is a guide on how to calibrate a pH probe.
