A GUIDE TO pH MEASUREMENT - Mettler Toledo

2008-3-19 · When measuring hydrogen ions (i.e. n = +1), the slope factor at 25 °C (298 K) has a value of 59.16 mV. This is termed the IDEAL SLOPE FACTOR. It follows that for a unit change in pH, an ideal measuring system will sense a mV change of 59.16 mV. This measurement of slope factor gives an indication of the performance of the electrode system.
