i need calibration solution for the ph probe of my desjoyaux JD Dual, what are the levels of solution to use for recalibrating the probe?

Good evening . Do you use ph 7?

Good evening, it's the first time I have to do it and I don't know if it takes 7 of 9 of 10

Can you give me your email tonight I will be at the office and I will send you what you need

as this is a desjoyaux swimming pool with a redox sensor, i cannot find the documentation for the JD DUAL 40 to find the information needed for recalibration.

Thanks for your help.

Thanks, I'll do that tonight. Have a good evening
