WebCalibration of any pH equipment should always begin with buffer 7.0 as this is the ‘zero point’. The pH scale has an equivalent mV scale. The mV scale ranges from +420 to -420 mV. At a pH of 7.0 the mV value is 0. Each pH change corresponds to a change of +/- 60mV. As pH values become more acidic the mV values become greater. bing hours
