Can the dissolved oxygen sensor be replaced?
Thread Content
The current dissolved oxygen analyzers in use are the E+H COM253 together with the COS41-2F sensor; now the COS41-2F sensor has been replaced because its import cost is too high, and we would like to use a domestic alternative – is such a product available? How about the model? Thank you!
Sure, but be careful with his moves
There are three main categories of methods for measuring dissolved oxygen online. One category is electrochemical methods, namely polarographic methods, which are the most commonly used； One category is fluorescent types, and currently only HACH Company and E+H Company offer them ； There is also a type of contact electrode type, which is available only from Zullig Company. I estimate that dissolved oxygen electrodes from different manufacturers are not interchangeable.
