    Go to somewhere that has a laboratory. They will have a pH meter and can calibrate. A university lab/a water testing lab should be able to do it and it will only take a few minutes and cost them nothing

    See the thing is its not only a one time calibration they say you need to calibrate the pen each time before usage

    Can you possibly remember the name or what your search was when you saw this?
