Issues related to pH meter selection and the process
Thread Content
Our factory uses liquid ammonia to adjust the pH value of the solution. The pH meters we have in use have a short lifespan and tend to break down easily; we’re not sure what type of pH meter would be suitable. Stirring is employed during the ammonia introduction process to ensure uniform distribution of the pH value throughout the material, but we’re not certain whether this approach is appropriate. What is the standard process for adjusting the pH value of a solution using liquid ammonia?
We use E+H models; there are multiple units of them, and their lifespan is quite long.
