Online instrument for detecting formaldehyde solution concentration
Thread Content
Does anyone know of any good online instruments for directly measuring the concentration of formalin solution, which can be installed on the pipelines carrying formalin solution to directly detect the concentration of formalin in those pipelines, without the need for density calculations?
An online densitometer or a mass flow meter can be used to measure density. The density of an aqueous formaldehyde solution is related to the concentration of formaldehyde.
I saw that density meters are used in many cases. . . .
We use mass flow meters, which rely on density conversion; as a result, the measurements are not accurate. It’s hard to fix now. Affect production
Is there anything better? There are products manufactured in Shenzhen, but I don’t know how to get in touch with them
I also think a specialized analytical instrument for detecting formaldehyde is needed; I’ll consult an online testing company
Is the original poster still here? I work in the field of iron, molybdenum, and formaldehyde as well. Can we be friends?
Is it testing only for formaldehyde? It is better to use online Raman spectroscopy
