I finally received my Hanna Instruments unit. It is a Model HI 9142.
I took some measurements around the pond earlier today and found pretty consistent readings of 7.4 - 7.5 mg/l. The booklet says the probe must be kept in motion? Anyways, I also took some readings in the flowing water of the stream on our property. I found the readings there to be only 4.4 mg/l.
The lower reading in the stream kind of surprised me because I know for a fact that it is loaded with Brook Trout. I would of thought that this moving water would have more oxygen in it?
Any thoughts on this?
