Compatibility and replacement of probes for AVADY STAR PH controller: Explanations and advice

My AVADY STAR PH controller was delivered with a 130 mm long probe (ELECT PH 120-2 AP) with the reference "Sonde AYAC08AC00" in the spare parts list of the documentation. Is this a delivery error or are both compatible? What do you recommend for its replacement as it is defective? Thank you for your response.

Hello,

The probe you received is indeed the one that is compatible with your controller. You can find it here: https://ph-redox-pool.com/gb/avady/3211-ph-probes-for-80-mm-avady--ayac08ac01.html

What is the difference with AYAC08AC00?

There is no difference, it is just an internal reference for AVADY.

Does anything change between 80 mm and 130 mm?

No, 80 mm is simply the length of the transparent part of the probe.

Thank you, I will place an order.

Thank you! Have a great day.
