a klereo compaq M5 ph probe to perform the calibration.

Hello I have a klereo compaq M5 ph probe to perform the calibration. I have to plan a ph7 and ph4 solution. Can I take a solution that is not from the klereo brand?

Hello, Yes the solutions are the same for all the probes. Only the value is important pH 4 .. pH 7 ...

OK so if the device indicates to me that the measurement is out of range. Does that mean the probe is fucked up?

Hello

Hello

You can do a test: you dip the probe in water and read the pH value

And then you add vinegar to the water

OK I test thank you and I tell you what

If the probe is out of service then the pH value will not move

Good luck. Do not hesitate to contact us again

Good day

Test performed. This went from 4.6 to 4.4 ...

And how much did you have in the water?

4.6

Yes 4.6

Well she has a problem in the water she should have read a value greater than 6 and the variation should have been greater than 2ph. How old is your catheter?

1 year

The increase in ph with the vinegar should have been immediate? I left it for more or less 2 minutes in a mixture of 10cl water 10cl vinegar
