What kind of hydrogen analyzer is good to choose?
Thread Content
I’m looking for an online analyzer from a domestic brand; I’m not sure if anyone has used them. Could you recommend a few brands?
In principle, hydrogen analyzers can be divided into three types: one is the thermal conductivity type, another is the density type, and the third is the chromatographic type. If high accuracy and reliability are required, chromatography is the most suitable method, as it can also detect various components other than hydrogen. Under certain conditions, the accuracy of the heat-conduction type is slightly better than that of the density type, but it requires constant-temperature measurement conditions and the gas composition should not be too complex.
