During calibration the value is 8.3

 If you have any questions, please let us know.

Hello I have a digi ph aqualysis device. Having doubts about the values, I calibrated the probe in a pH 7 buffer solution. During the calibration the value is 8.3. The probe is 2 years old should it be changed and if so is it compatible with the one you are offering. Thanks for your help

Hello

Take a first test:

1) Put the probe in water

2. Read the pH value

3. Add vinegar to the water

4. Read the value of Ph

OK I will test thank you. I have to read a particular value

If the pH value does not vary by at least 2 pH then your probe is out of service

OK it's noted thank you

This is just to check that the probe is still reacting.

Then for the values ​​it can be a problem of standard solution - Regulator or a very tired probe

The buffer solution is new bought yesterday

Check the probe, and do not hesitate to contact me

I do that

Thank you very much for your help
