Dissolved Oxygen Kit


There are basically two easy ways to measure oxygen dissolved in water:

You can guess and then insist that you measured it, which has the obvious disadvantage of being wildly inaccurate; or you can just use the Atlas Scientific Dissolved Oxygen Kit.

Available in 4 to 6 days after ordering

If you are new to electrochemical sensing, knowing what components you need can get confusing. Let us help you.

The Atlas Scientific EZO-Dissolved Oxygen Kit gives you everything you need to take high accuracy, interference-free readings. Once you become familiar with electrochemical sensing, it will be easy for you to streamline your design and buy only the components that work for you.
