Which brand is better for the refractometry method to determine ammonia concentration?

Besides EMC, which domestic brand is good? Is vibration better or is the refractometry method better?
Ammonia water has significant volatility and solvating properties; small bubbles will form in the solution, right? As for the number and uniformity of the bubbles, I’m afraid they aren’t fixed either, right? . . . Every small bubble that the light wave encounters changes the path of propagation of the light as well. . . For some things, by analyzing them based on the principles of measurement, it is possible to determine whether reliable measurement results can be obtained, without the need for practical experimentation.
K-Patents is also good, the refractometry method； Anton’s sound-speed density method is effective for measuring sulfuric acid concentration. I’m not sure if ammonia can be used for measurement.
The ammonia solution now contains a small amount of sulfurous acid; refractometry cannot be used at all. What should be done?
Question: Does the an content of sulfurous acid vary, and is the range of variation large?
It is almost never done to measure ammonia added to demineralized water. Cleaning too frequently. I wonder if the vibration method is better?
In the presence of ammonium salts, the sensor is highly susceptible to low-temperature scaling caused by salts in the medium； It is recommended to use the online automatic mechanical brush cleaning mode ；
Kapast is not good; the vibration method is recommended
The refractometry method is accurate, but it becomes ineffective once it gets dirty, and its maintenance requires a lot of effort
It can be paired with an online mechanical brush cleaning device, requiring no maintenance!
