May 23, 2014It consists of NH3 and NH4+. As I know, to determind the concentration of NH3, we have to measure the pH and total concentration of ammonia. I measured the pH and now, I need a sensor to measure the total concentration of ammonia. If you know any sensor with cheper price, please give me. Sorry about my bad english. Thanks you very much.Sensors for Ammonia/Nitrate/Nitrite? - Hardware - Particle
