WebWith pH 4.00 calibration buffer, the output voltage is 168.8 mV. This gives a range of 168.8 - 4.6 = 164.2 mV for 3.01 pH units, or 54.55 mV per pH unit. If, for example, I measure 100 mV, the pH is 100 mV / 54.55 mV = 1.83 pH units deviation from 7.01, so I subtract 1.83 from 7.01 for a pH of 5.18. darling\u0027s fine things newport ar https://martinwilliamjones.com
