online ammonium ion detector
measuring principle
The selective electrode of online ammonium ion detector is an effective method to measure the ammonia nitrogen content in samples. Ammonium ion-selective electrodes are also often used in on-line instruments, such as the determination of ammonia nitrogen content in water.
Ammonium ion selective electrode has the advantages of simple measurement and accurate response. It can be used by PH meter, ion meter and online ammonia nitrogen analyzer. It is widely used in biological samples ammonia nitrogen, soil ammonia nitrogen, surface water ammonia nitrogen, sewage ammonia nitrogen, and the online determination of ammonia nitrogen in water.
Application:
ammonium ion measurement of boiler feed water; ammonium ion measurement of surface water, ammonium ion measurement of fertilizer.
