Contact: Hello! I have an Etatron system and I need a new pH probe.
Advisor: Hello! One moment please... Here is the probe you need: pH probe for Etatron.
Contact: Does it fit on a system "CXB4000301"?
Advisor: Yes, the probe fits on that system.
Contact: Is it a REDOX probe or a "normal" one?
Advisor: Are you looking for a pH probe or a Redox probe?
Contact: If only I knew.... 😉 I want to replace my current probe, how can I determine which type I have?
Advisor: What does your device read?
Contact: On my device, I read the pH value. I wanted to calibrate the probe, but it never reaches a value below 8.9 in the pH 7 solution. So I think the probe is broken.
Advisor: In that case, it's quite possible that the probe is defective. Here is a link that can help you with the verification: Is my pH probe defective?.
