I forgot Cap.You mean that website posted, where does it say Hanna says that on their
website seawater ?

I would also like to know how this unit can measure DO without out adjusting for Salinity
and barometric pressure. Neither are listed. If it has such a salinity adjustment it would
say so, as all meters that do say so.

Here is more info on it .Nowhere does it say "seawater"

: How interesting though, Boomer. It is funny when you mention this
: "photometer" are FW meter but according to their site, it statement focus on
