The Effects of Temperature on PH Measurement
knowledge.reagecon.comthe correct buffer is used. Meter manufacturers generally specify specific pH buffer types to be used for calibration - for example some pH meters can be calibrated using technical pH buffers or DIN/NIST buffers (values specified at 25°C) (11). Use of the incorrect buffer type can lead to inaccurate calibration and hence incorrect pH measurements.
