Troubleshooting Peristaltic Pump Series Epool PH: Addressing Constant pH Value and Electrode Calibration Issues

Client:
Buona sera, ho acquistato 3 mesi fa un pompa peristaltica serie epool ph ma dalla prima installazione il valore ph era a 6.8 e non varia mai. Sembra che l'elettrodo non legga il valore. Perché con uno strumento esterno il valore ph è superiore e al momento andiamo a correggere il valore intervenendo a mano.

Technical Advisor:
Good evening, I understand your concern regarding the peristaltic pump series epool ph that you purchased 3 months ago. It seems like the electrode is not reading the value since the pH value has been constant at 6.8 since the first installation. This could be due to various reasons. One possibility could be that the electrode is not calibrated correctly. You mentioned that you are using an external tool to measure the pH value and it shows a higher value. It would be helpful if you could provide more details about this external tool. Meanwhile, I recommend checking the calibration of the electrode. Here is a link to a guide on how to calibrate the electrode: www.electrodecalibrationguide.com. Please follow the instructions and let me know if the problem persists.
