Client:
Hello.

Technical Advisor:
Hello.

Client:
I want to change my POH PROMINENT PHEK 112 FE 303 B probe for my IDOIT. What model do you suggest?

Technical Advisor:
One moment.

Technical Advisor:
For the idoit, we have this one https://ph-redox-pool.com/gb/régul-électronique/2954-ph-probes-for-idoit-regul-electronique.html

Client:
Do I not need the one with redox for 128 €?
I can send you a photo of the probe if you want...

Technical Advisor:
The one I am suggesting is a pH probe
Yes, send me the photo
Or do you want the redox probe?

Client:
What is the redox for?


Here are the photos.

Technical Advisor:
It is another measurement. The probe in the photo is indeed a pH probe.

This is the one.

Client:
Okay, great. If I buy 2, will the other one stay new to replace in 2 or 3 years?

Technical Advisor:
No, the probes do not stay new for that long.
