Nitrate Nitrogen (NO3-) Meters

 
The following meters are meters that have ion selective membranes that selectively trap the nitrate nitrogen anion and is able to measure in ppm the amount in solution.
 
Nitrogen is essential for good growth and high yields, especially in a plants early growth stage. It is therefore very important to be able to accurately measure how much nitrogen you need for your soil, your fertilizers, in the leaves of your plant.
 
However, too much nitrogen in human and animal feed can cause Nitrate poisoning and has been associated with cancer, so it is also important for health purposes to be able to measure Nitrate Nitrogen content of your foods.
