Hello

Can I help you ?

Yes please

I have a bio UV pH regulator with dosing pump

I have a doubt about the pH value and I can't calibrate the probe

I would like to change it

the regulator must be about 15 years old

In this case start by doing this test; https://ph-redox-pool.com/gb/content/16-ma-sonde-ph-est-elle-hors-service-

I put it in 3 solutions at ph 4, 7 and 10 and the value moves

And why are you in doubt?

ph of my swimming pool at 8.6 without moving, it constantly injects me with ph -

it's weird

the water is new this year, it never did that to me

Ph at 8.6 these very strong. when you dip your probe in pH 7. what value do you read?

water test at 7, ph given at 8 by the device, hydrochloric acid put in, ph increased to 4

the ph meter seems to be working

water at 7 per ph paper

OK, there is a problem with the calibration! I'm thinking of trying to calibrate again

thank you sir, have a nice weekend

thanks for your advices

The principle of calibration is that when my probe is in the standard solution at PH 7 then my device displays 7
