pH meter calibration question? | Yahoo Answers
Nov 13, 2011The buffers used are of pH 3, 7 and 10. Now, you can calibrate the pH meter to take readings from pH 3 to 7, pH 7 to 10 or from 3 to 10. It all depends on what the range is. If you only want to measure a pH at pH 7, I would perform a 2 point calibration at 20 degrees C (because pH is temperature dependent) using the buffer pH 7 and buffer pH 10.
