Hello, I am looking for a PH probe for my HAYWARD EZ-Chem regulator and I see that you have 2 models: PH1-3-0092 at 59 € and PH1-3-0312 at 63 € ... Can you could you explain to me please? thanks in advance
The one at 59 € does not have the probe holder. The one at 63 € is delivered with the adapter because sometimes the original one is difficult to recover
