WebCircuit Description Fundamentals of pH Measurements The pH value is a measure of the relative amount of hydrogen and hydroxide ions in an aqueous solution. In terms of molar concentrations, water at 25°C contains 1 × 10 −7 moles/liter of hydrogen ions and the same concentration of hydroxide ions. WebTotal pH range is 0 (strong acid) to 14 (strong base) If probe generates -59mV/pH unit then our effective range would be +/- 7*59mV or +/-.414volts Depending on temperature the voltage generated per pH unit varies from … inclus date
