What type of instrument are oxygen analyzers, as well as online analyzers for sulfur content?

Is there any teacher who can explain this? Thank you
It depends on how you classify them – by principle or by method of use. For oxygen analyzers, there are those based on electrochemical principles, zirconia technology, paramagnetic methods, as well as those that use lead acetate hydrogen sulfide paper or lasers.
What exactly do you want to ask? I have previously come into contact with two types of acid-producing oxygen content analyzers – one for negative pressure and one for positive pressure – as well as one SO2 analyzer. The oxygen content analyzer uses zirconia, while the SO2 analyzer relies on ultraviolet light; you can refer to the manuals for these analyzers for more details

They all fall under the category of online analysis; I’m not sure what you want to know
Under this broad classification, it falls under testing instruments; analytical instruments refer to things like chromatographs and mass spectrometers.
