Hello, I recently bought a PH and RSDOX probe for soleo Pentair. After replacing the PH probe, I carried out the calibration, everything is OK.

Great !

when I put the probe in the jar it indicates 8.6 When I take it out of the water it goes down if I immerse it in the liquid 7 it indicates 7 and in the 4 it indicates 4. but in the water of the swimming pool it rises to 8.6.

Pool water is at 7.6

How do you know the water is at 7, 6

test with a scuba II and confirm with a KIT test

So have a drink, put some water from the pool. And redo the measurements. or measure your solution at pH7 with your scuba II

it's already done everything is good

OL happens that when I cut off the water supply from the probe jar that the pH returns to 7.6 but when I pressurize the jar the pH goes back to 8.6

So it looks like the probe and the scuda agree on the measurement. Do you think the probe dips well in the liquid?

yes I tried different setting it's the same

when it does not dip it goes down regularly

In summary, If you take a glass of water with water from the swimming pool. The scuda measures 7.6 and so does the probe. the worry comes when you put pressure

not always with tap water in a glass it also goes up to 8.6

Can you do one thing: dip the probe in a glass of water and come and see the measurement 3 to 4 times a day to find out if the measurement is stable

I have been struggling with it for 4 days now I will try but I am afraid the result will remain the same. Do you know a convenience store in Frejus?

What you are describing to me is curious and rare. when you write "a drink it also goes up to 8.6" does the value go down to 7.6 after a while?

No, it's stuck on 8.6.

And if after, you put it in pH 7 it returns to 7?

Yes it comes well at 7 or 4 depending on the liquid I have just put it in a glass I will check several times during the day.

It's really strange ! Check anyway that the scuba II measures the solution PH 7 to 7

Tell me the result

It's already done I've been tearing my hair out for several days with a bunch of tests and confirmations

Try this: the scuba II measures the PH 7 to 7 solution well.

Yes I did it to validate the scuba II because I had a doubt too

Tell me later if the measurement is stable

If yes, we replace it afterwards

Ok thank you I will contact you tomorrow

Okay . Have a good day

Hello,

Hello

Hello, I come back to you for the PH probe.

I put the probe jar back in its old location and everything seems to be back to normal. It seems to be an electromagnetic interference problem.

Thank you for your patience and your answers have a nice weekend

It is possible, at the slightest concern you contact me. If necessary we will change it

Have a nice week end
