Portable dissolved oxygen analyzer
Thread Content
Are there any portable dissolved oxygen analyzers with extremely high precision, at the PPB level? It would be ideal if they could measure in the range of 0-10 PPB
Theoretically, it can’t be that precise; I’ve never used one. 1 ppm equals 1000 ppb, and generally, portable oxygen concentration analyzers don’t achieve a precision of 1 ppb, let alone in a measurement range of 0–10 ppb. What is it that you want to measure?
Regarding the usage environment, brand requirements need to be specific in order to make a recommendation.
The technical requirements specify that this precision must be achieved
It’s best to choose a brand-name one; as long as it has the required measurement accuracy and functions properly, that’s fine.
Have you never heard of the Honeywell brand?
They don’t have this product, do they? It can’t be found online either.
I’ve never seen industrial production reach the ppb level~ Please provide some information on this
