The invention relates to a furnace water pH temperature compensation measurement method and device based on phosphate treatment, and the method comprises the steps: 1) measuring temperature compensation under different medium conditions and different temperature conditions and m groups of temperature compensation fitting curves of different phosphate radical concentrations cm according to adjustment of phosphate, pH and measurement temperature of a water sample; (2) the boiler water sample to be measured passes through a pH sensor, and a temperature value t and uncompensated pH x are obtained through measurement; and 3) substituting the measured temperature value t and the phosphate radical c into a specific fitting curve to obtain a corresponding precise temperature compensation value of the pH value of the boiler water subjected to phosphate treatment, and carrying out compensation calibration on the uncompensated pH x according to the temperature compensation value. Precise compensation of the boiler water
