Choosing the Suitable Probe to Test Chlorine and pH in a Pool: Practical Guide

Client:
I'm looking for a probe to test chlorine. Does this article fit? PH/CHLORINE pH

Technical Advisor:
What regulator do you have?

Client:
LMP

Client:
Thank you. And for the pH test probe?

Client:
Is it the same?

Technical Advisor:
There is a pH probe and a redox probe

Client:
Ah ok. So reference 3327 is for pH and 3328 is for chlorine. Could you also give me the references for the calibration solutions to use for both probes?

Technical Advisor:
Yes, chlorine = redox. Do you use PH7-PH10 and 465 mV?
