[compost_tea] Re: oxygen meter



I know we've been through this before but I cannot find the posts in the
archives ;-(  

I would like to find a good quality Do2 meter. Ideally I'd like to be able
to use it inline for constant monitoring. Elaine mentioned one in NZ which
was connected to an air valve which I realize is a very expensive option.
I'd be happy if I could set limits and have an alarm sound if the tea so
going anerobic.
