Client:
Hello, I have a microdos control unit.
Technical Advisor:
Hello, which model?
Technical Advisor:
No, sorry!
Client:
Do you not know the control unit or do you not have this probe?
Technical Advisor:
I don't have the probe.
Client:
Do you know where I could find it?
Technical Advisor:
Your probe seems different.
Technical Advisor:
You have the free chlorine (CL) sensor which is different from the redox sensor.
Client:
Yes, could you direct me where to find this probe?
Technical Advisor:
Sorry, I don't know.
Client:
Ok, thank you.
Technical Advisor:
Have a good day.
