Efficient customer service: Resolving a pH and Redox probe issue.

Client:
Hello

Technical Advisor:
Hello

Client:
Two years ago, I bought two probes, one pH and one redox. Today, I have a small problem: the free washer with the probe that held the probe in the analysis chamber broke and the probe no longer stays in place. As a result, as soon as I put water in the analysis chamber, there is a leak.

Technical Advisor:
Can you give me your name?

Client:
Zanouji. Here is my previous order WMDCGCKFW.

Technical Advisor:
On Monday, we will send you 2 washers. Is that okay for you?

Client:
That's perfect, thank you very much. Do you have my contact information?

Technical Advisor:
Youssef Zanouji, 74 avenue de rosny, 93130 Noisy Le Sec, France. Is that correct?

Client:
Yes, thank you. I also have another question: how often should the probes be replaced?

Technical Advisor:
There is no specific rule, but you can test your probes like this:
For the pH probe
For the redox probe

Client:
Ok, that's great. I will try. Thank you for your help.

Technical Advisor:
You're welcome. Feel free to contact us again! Have a nice day.

Client:
Have a nice day too.
