What is this “standard fluid”? Is there a household fluid that has standard ORP readings? Maybe medical 3% h2o2? Or maybe Clorox bleach? 🤷♂️ My meter has an analog dial so I can adjust it to anything. Thank you!!!
I heard green tea has a negative ORP around -120. I have not been able to confirm that with an ORP meter. Suggest to use an ORP calibration fluid as a standard fluid. But I don't know if different meter brands have different calibration fluids, so not sure what "standard" means?
@@ktsmith1450 I just use my PH calibration fluid and find the difference between the two. ORP meter is best used as a comparison and not an accurate measurement from my experience
What is the recommended buffer solution for 54E ORP ? For Chlorine Application
