I have a question. For dissolved oxygen measurement, will that bubbles that came out when you first opened the lid be a problem? The bubbles seemed to go out of the bottle, but were they really? Won't they affecting the oxygen collected in the bottle?
Thanks please can you do a video to differentiate between grab sampling and composite sampling methods
Great video, to the point and educational
thanks this was helpful
