Guide for replacing and calibrating the pH probe of a Stérilor Duo device.

- Categories : Questions about RedOX probes

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 that 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 have 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 also find the values in the manual.

I'll go check, I'll be right back.

It says: immerse the electrode in a pH 7.01 buffer solution...

Ok.

This is the calibration for 7 (neutral). Further down 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 a 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, it's fine, but we don't sell those.

Alright, thank you very much. I will place the order. Have a good evening, thank you.

Thank you, have a good evening.
