Can’t really tell if this is accurate since I have nothing to compare it with. However, it’s pretty simple to use. The procedures are easy to follow. Just hoping for the results to be accurate. I used it to monitor my fish tank DO. A little expensive, I’d be more satisfied if the cost was slightly lower. But, it’s a cheaper alternative to a DO meter.

I use this to test my aquarium water and it was really easy to use and had some awesome water bottles that were reusable with corked tops! So amazing, really easy to use and the instructions were easy to follow as well.

I have used multiple times and get the same readings when I should not. I don't think it is accurate or the instructions or chemicals are wrong. I teach science and used for labs. Could not get readings to differentiate extreme hot vs cold water. Hot (212 degrees) should have much less oxygen.
