Hello there, I'm new in this forum and i don't have much knowledge in chemistry. I need help in a question that may help me a lot in my research "measuring dissolved oxygen for aquaculture purposes". The problem is that the sensors i need to measure the DO are too expensive and i need a more cheap and automatic way to do it. I was searching over the internet and found about other metric, called Redox, which is related to the Oxidation-Reduction Potential (ORP). Then i thought that maybe this metric could be used to measure the DO, because both are strongly related to the oxygen. Does this make any sense?
Sorry my lack of knowledge, but i didn't know where else to find help. Thank you for anyone available to help.
