False alarm. This won't work with compost teas as the
test relies on water being colorless which compost tea
isn't. Sorry.

Subject: [compost_tea] Oxygen Tests
 
I've been looking for a DO meter and re-reading some of the posts.
I'm not a scientist and I don't think I'd care to constantly recalibrate
a DO meter as some on this list are doing. In researching this, I'm
also hearing from you that these meters are pricey.
 
I asked my club members if someone had a meter and one member
who's retired from the oyster business loaned me his dissolved oxygen
test kit by Hach, Model OX-2P.
 
I've just read the instructions which seem straight forward. The kit
looks easy to use. I phoned the manufacturer
and had all my questions answered. These kits only cost $47.75 and are
good for 100 tests. Hach also sells DO probes. They're in Colorado.
