How to solve salinity measurement issues with the Hayward Rx Socket controller: practical guide and tips from a technical advisor.

Client:

Hello, I have a Hayward Rx Socket salinity controller (conductometer). The probe does not give the correct value during calibration, and the screen shows RC --> probe change required. Do you have this type of probe in stock, and how much does it cost?

Technical Advisor:

Hello,

I think it is a redox probe (measured in mV). In this case, test it like this:

The replacement probe is this one:

In stock. Deliverable in 4 days.

Client:

Thank you. I will perform the test. The current indicated value is 80 mV, but the electrolysis is working fine and even providing too much active chlorine.

Technical Advisor:

80 mV is suspicious. Perform the test and let me know the value before and after adding salt.

Client:

I will do that tonight and contact you again if it is faulty. I will keep the references and contact you if necessary. Thank you and kind regards.

Technical Advisor:

You're welcome. Feel free to contact us again! Have a good evening.

Client:

I will order it. Regarding the calibration buffer solution, Hayward indicates in its catalog a solution with a potential of 468mV. Do you also have this solution, so I can buy everything at once?

Technical Advisor:

YES, just a moment.

Here is the link to the solution:
