In part two of our NeoFox tutorials, we show you how to perform a two-point calibration. In this example we will be using Nitrogen as the Zero percent Oxygen standard, and room air as our second standard at 20.9% Oxygen. If you have not setup your NeoFox software, please view the first video in the series for help doing so. For more information, visit www.oceanoptics.com/Products/neofox.asp
