Hello , does the PH probe for Hayward fit all devices or does something have to be considered here?

Hi

What model of Hayward controller do you have?

Where can I find this information?

You can send me a photo of your current probe or case

Or does your current probe look like this?

OK one moment .

for RedOX

our PH probe is broken, do I have to replace both?

no

https://ph-redox-pool.com/de/hayward/1711-pH-sonde-für-AQUARITE-pro-DE-HAYWARD.html I found these anyway, then I can order them without any problems

Many thanks for the help!

If the pH probe doesn't work, then only the pH probe

Thank you very much for your help

Yes you can order, they are in stock.
