Exchange between a customer and a technical advisor on Maestro pH and ORP probes

Client:
Hello again, sir. I just called you about the Maestro pH and ORP probes. I measured the length of the wire on the installation, and it is more than 35 cm.

Technical Advisor:
Hello again, sir. How much do you need? 50 cm?

Client:
Yes

Technical Advisor:
OK, I'll do that for you. I need your name!

Client:
JEAN-PIERRE Grégoire

Technical Advisor:
Are you ordering today?

Client:
I will proceed in two steps. I am about to order a pH probe and two ORP calibration solutions. If the ORP probe turns out to be faulty, I will order one separately at a later time.

Technical Advisor:
Otherwise, remind me before placing the order.

Client:
Yes, I am ordering a pH probe + calibration solutions today.

Technical Advisor:

I'll prepare a pH probe at 50 cm for you.

Client:
Oh, thank you for the ORP test. What is the lifespan of such a probe?

Technical Advisor:
82% exceed 3 years.
