Thread Content
This post was last edited by “Back to Cambridge” on September 28, 2016, at 09:28. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequently, series such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will be introduced. We hope for your active participation! Wishing you all a Merry Christmas~~ For replies to the “Question of the Day” activity, answers can be viewed directly; however, the thread will be closed after one day! ! To encourage continued participation from everyone this year! You get 3 wealth rewards just for participating, and an additional 4 wealth points for correct answers~~~ Short answer question: How can you determine if a pH electrode and a PNa electrode are aging? Answer: Generally, if the positioning time exceeds 10 minutes and the pointer continues to drift slowly, it indicates that the electrode is aging and its response is sluggish; in such cases, a new electrode should be replaced.
If the positioning time exceeds ten minutes and the pointer continues to move slowly, it indicates that the electrode is aging and functioning poorly; in such cases, a new electrode should be replaced.
If the positioning time exceeds 10 minutes and the pointer continues to move slowly, it indicates that the electrode has degraded and its response is sluggish; in such cases, a new electrode should be replaced
By observing the pointer, if it continues to drift slowly over an extended period, it indicates that the electrode is aging
If the positioning time generally exceeds 10 minutes and the pointer continues to drift slowly, it indicates that the electrode is aging and its response is sluggish; in such cases, a new electrode should be replaced.
Generally, if the positioning time exceeds 10 minutes and the pointer continues to move slowly, it indicates that the electrode is worn out and its response is sluggish; in such cases, a new electrode should be replaced.
(1) Slowed response (2) Increased impedance (3) Reduced slope (4) Drift in zero point
