    Hayward pH & ORP probes: Sense & Dispense vs. CAT2000/4000

    Hayward offers their series of CATx000 commercial systems for monitoring pH and ORP. The probes used for these systems look just like the probes used in the residential sense & dispense system. A pair of replacement probes for the residential sense & dispense costs almost as much as an entire new sense & dispense system. I can get probes for the commercial CATx000 system for less than the price of the GLX probes for the sense & dispense.

    You know what they say about a deal that seems too good to be true. So I have ask if there is there someone (in the business?) on the forum who can verify whether both systems use the same probes?

    I can't answer but maybe someone will know.

    I am wondering the same thing. I have a Wwatermatic D-1 with a C2000 controller. The probes are approx $200 each. I just bought probes from Test Equipment Depot: Milwaukee MA913B/3 Combined Epoxy pH Electrode & Milwaukee MA923B3 ORP Probe with 3 Meter Cable. Both have BNC connectors and were approx $40 each. They are made for pools according to the Test Equip Depot. I am going to install them this weekend. We will see if/how they work.

    You might want to check into Atlas Scientific. Their probes that I use are around $70~ each.
