WebbFor pH electrodes, the theoretical mV value at pH 7 is 0mV (neutral) and the slope of the line is 59.16mV. This means that in theory the electrode will change its output by 59.16mV for every pH unit you go (e.g. pH 6 to pH 7 would be 59.16mV/pH unit). All of this is in theory since electrodes will change their slope and offset as they age.
