What can you do with the DO? This month we have two activities that make use of our Optical Dissolved Oxygen Sensor— a sensor that makes DO sensing easier and more accurate than ever before. Read more about what NSTA's Technology, Science 2.0 blog recently said about our ODO sensor after putting it to the ultimate field test. 

We have a free lab to help you put it to the test. Take a look at our latest blog entry to see what happened when we created a model for biological oxygen demand (BOD) in an aquatic ecosystem using just milk as our organic pollutant and yeast to model decomposers— and thendownload the free lab to try it with your class.  

Increase Productivity
Our ODO Sensor and Aquatic Productivity Bottles make determining net primary productivty easier than ever. Check out the results in this short video!
