Resolution of discrepancy between the pH display of the Nike pump and the one in the basin.

Client

Hello, I have a nike ph pump and the ph display is at 7 while my pool is at 9. I have already calibrated it but it remains at 7. Do you know what I should do? Is it necessarily a problem with the probe?

Technical Advisor

Dear customer, it does indeed seem that your PH probe may have a problem. However, before concluding, I advise you to proceed with a new calibration. If the problem persists, it would then be necessary to call a technician. You can schedule an appointment online via this link.
