Dr. Ingham asked me to post info on the dissolved oxygen
meter we use so here it is:
Extech Dissolved Oxygen Meter, Model 407510
We got ours out of the Grainger Industrial Supply Catalog,
www.grainger.com , (order No. 4KC32 $399) with the
additional software for making automatic interval
measurements on a P.C. (No. 3ZH85 $49). The software is
only neccesarry for recording measurments when the operator
is not present to take a reading.
I believe Grainger may only sell to companies and not
individuals, so if anyone finds another retail source, let
us know.
Thanks,
Charles
