Hello, I have a Sterilor Duo device from 2013. I want to replace the probe, which probe should I choose?
Hello,
The pH probe?
Yes, I found one, the reference is PH-1-3-0114.
Is it the right one?

Yes, that's correct.
Great, thank you. I also need to calibrate it. How do I do that?
Do you have the manual for your regulator?
Yes, I need to look for it in the technical room. Do I need to buy something to calibrate it? I've never done it before.
Yes, calibration solutions.
Can you recommend some, please?
You will find the values in the manual as well.
I will go check, I'll be back.
It says: immerse the electrode in a pH 7.01 buffer solution...
That's the calibration for 7 (neutral). Further on, it says: Calibration for 10 (slope) - I don't understand why there are 2 options. Do I need both (neutral and slope)?
Yes, it's the 2-point calibration method, one moment.

It also says that the inner core and latex should be replaced after 800 hours of operation (which has long been exceeded).
If it's working, then it's fine, but we don't sell those.
