Abstract

The embodiment of the invention discloses a pH value measuring method. The pH value measuring method comprises the following steps: simultaneously measuring pH values in three positions in a reaction kettle; judging whether a first pH value is unavailable according to the difference between the first pH value and a second pH value as well as the difference between the first pH value and a third pH value, wherein when the first pH value is available, the average value of the three pH values is taken as the pH value of a solution in the reaction kettle, and when the first pH value is not available, the average value of the second pH value and the third pH value is taken as the pH value of the solution in the reaction kettle. According to the pH value measuring method provided by the embodiment of the invention, when a certain pH meter malfunctions, the fault can be timely found, and the pH value measured by the malfunctioned pH meter is removed when the pH value of the solution in the reaction kettle is calculated, so that the measurement accuracy of the pH value of the solution in the reaction kettle is improved, and the control errors of the pH value of the solution are reduced in a production process. The application further discloses a pH value measuring device.

Description

technical field [0001] The invention relates to the technical field of measurement, and more specifically, to a method and device for measuring pH value. Background technique [0002] In the production process of pharmaceutical production, sewage treatment, preparation and petrochemical, etc., it is necessary to accurately control the pH value of the solution, and the key step to control the pH value of the solution is to obtain the pH value of the solution. [0003] At present, the method of measuring the pH value of the solution is to install two pH meters on the reactor (a container for related reactions) to measure the solution in the reactor, and take the average of the pH values ​​measured by the two pH meters as the reaction The pH of the solution in the kettle. [0004] However, in the current pH measurement method, when a pH meter breaks down, it cannot be detected in time, which makes the measurement of the pH of the solution in the reactor inaccurate, and causes ...
