Differences between buffer solutions and their role in pH probe calibration.

Client:
Hello, how do the different buffer solutions differ from each other? Do I need all of them to calibrate a pH probe (for oxilife), or is pH 7 sufficient?

Technical Advisor:
It depends on the controller.

Client:
What does that mean exactly?

Technical Advisor:
You need to read the controller's manual.

Technical Advisor:
Oxilife.

Client:
OK, I will check if I can find anything there. I have the Oxilife 1.
