: I'll be short. :-) You will get a reading but it is not correct, just like a refract or
a
: pH meter or most pH kits. Did you know that a pH meter and most kits DO NOT test
seawater
: accurately . It is something we call the "Salt Effect". There are actual seawater stds
for
: pH, i.e, pH nist (FW) and pH nsw (seawater). Your pH meter actually reads to high just
as
: some test kits do. Randy will be doing an article on this later. We do not need to be
all
: that concerned for the meter ? Most given pH seawater meter values ( oceanography books,
: articles etc.) are uncorrected. Some pH kits give you seawater corrections or are
adjusted
: for seawater. This is why some get confused when comparing kits. But they still sell
them
: now don't they for seawater. Same for the CO2 test kit, sold for seawater, IT WILL NOT
: WORK PERIOD. Seawater is a unique medium and often messes up tests. As I have said a
: meter measuring O2 most be correct for seawater and if it had such a correction where is
: in on their website. Cheap O2 meters that use an O2 probe often give tables for
: correction.
:
: "And by using this meter to do an
: aquaculturing or farming testing."
:
: 99 % of the time this is FW
:
: "A normal person [non chemist] would assume this meter can be use to
: test sea water parameter"
:
: I agree. We have brought this up many times on our chem forum, go for a look. Randy has
: NEVER said I'm wrong but wonders if it really works as claimed.
:
: It is a photometer, works off of light, light does not travel the same in seawater as
FW,
: same reason a refract is off 1 unit right out of the box. But what do many of the
websites
: say. To measure salinity or seawater. There is only one refract on this planet that
: measures seawater you can buy and costs about $400, all the rest or set to NaCl, which
: again is not seawater. I also don't think much of Hanna they are a very bottom self
: company. It was me that got their cheap ORP off the market they were selling to reefers,
: as it didn't work. If you have any doubts call Hanna or HACH or LaMotte. Don't ask for a
: lab tech either, they are usually brain dead, ask for the guy the designs and tests
them.
: I did and the answer was NO, not accepted for seawater, that was HACH and all these
meters
: work the same, they are Photometric colorimeters. Their meter also says seawater. Ask
then
: for a data sheet of a know concentration and how their meters compares, you won't get
one,
: as they don't have one
:
:
: Here is a classic example. I did some private work for HACH years ago when I bought
their
: Seawater Aquaculture FF-3. I proved to them their CO2 kit can not work in seawater. The
: guy that runs this section is/was Dave Corzat. I proved it, Frank Millero (this is who
he
: is
http://www.rsmas.miami.edu/groups/jmc/fla-bay/fbay.html ) and Ed Mowka (
former
: President of Aquarium Systems). One reason for you to see why it doesn't work CO2 Range
=
: 10 -100 mg / l. You could not get 10 mg / l CO2 in seawater.let alone 100mg / l in
: seawater.About the highest you could get is around 2-3 mg / l. Normal levels are usually
: less that 1 mg / l NSW is 0.50 mg / l . How the hell can it do that when it must start
: at 10 mg / l,..... 2 mg / l let alone 0.05 is waaaaaaaaaayyyyyyyy outside its range.

http://www.hannainst.com/products/ion/c203.htm
: : AquaStore using the statement from Hanna site but omit some small detail

: : It is interesting how Hanna start from how fish is depleting from open sea
: : and need to aquaculturing then next use pond water to test.
: :
: : So what this meter is use for if not for testing sea water parameter?
: : I am at lost here. 8(. Boomer, I know and hearing from you that there no sea
: : water standard to go by or no meter available to accuately enough to be test
: : with. And yes, Hanna site does not that I can find anything specific that
: : indicate to test sea water regarding using this meter.
