How to conduct the dissolved oxygen test

As part of our Freshwater Explorer testkit, is the most 'sciency' of our tests! This test has been compared against professional probes, with great results that our scientists were pleased with! We use the chemmets kit, since we love how it works. But, we don't recommend it for kids under 9. Be careful with glass, and remember to take your garbage away with you. 0-2 mg/L: not enough oxygen to support life 2-4 mg/L: only a few fish and aquatic insects can survive 4-7 mg/L: good for many aquatic animals, low for cold water fish 7-11 mg/L: very good for most stream fish For more information about our freshwater kit, go to https://store.waterrangers.ca/product...
