Client:
Hello, I would like to know if the pH probe needs to be cleaned from time to time.
Technical Advisor:
Hello, no, it is not necessary.
Client:
I have a pH measurement of 6.5 which is not possible in my pool and the test strips also show more than 7.
Technical Advisor:
Do this quick test https://ph-redox-pool.com/gb/content/16-ma-sonde-ph-est-elle-hors-service-
Client:
Ok, I will do the test.
Technical Advisor:
👍
See you soon.
Client:
Well, if I test with the calibration solution which is at 7, the pump screen shows 6. If I add vinegar to the water, it goes down to 2.5. So the probe seems to be working, maybe the pump calibration is off?
Technical Advisor:
You need to calibrate it.
