Which model of pH meter should be used to measure the pH of the reaction tank under normal pressure at a rotation speed of 85 r/min, when the medium is flammable and explosive with a viscosity of 1-2 Pa·s?
Questions like this generally don’t yield any useful responses, but they might attract boastful posts from people trying to sell products. For your specific question, you should mention details such as the medium conditions, process parameters, and measurement requirements. Another important thing to remember is that for special problems, one should not expect to find cheap solutions or inexpensive products to address them.
Given the high viscosity of the liquid, should a pre-pressurized PH electrode be considered? As for process connections and transmitters, choose them according to the actual conditions.
Other parameters that need to be provided include temperature, medium composition, etc.
