Dear all,
I am doing a project in hydrophonics. I am struck in selecting sensors for my work. Can you please suggest me sensors for the following..
1. Measuring the amount of oxygen in water.
2. Measuring the amount of carbon di-oxide in air.
Thanks,
Prabhu P
Prabhu,
There are many ways to measure these gases:
Carbon dioxide can be well-measured using NDIR methods.
I have had good success with the sensors from:

and, more expensively, these:

(they require a sampling pump - but are more accurate)
For dissolved oxygen, there are a variety of sensor types:
There are galvanic:

And there are fluorescence-quenched methods:

James Garry and Sina Moghbeli thank you for the suggestions. I will work on those products and if any doubts, will get back to you....
