BH-485-NH DIGITAL RS485 AMMONIA NITROGEN SENSOR

The digital ammonia nitrogen sensor was measured by an ion selective electrode method. The ammonium ion selective electrode directly detects the ammonium ion in the water environment to determine the concentration of ammonia nitrogen. Use a pH electrode as a reference electrode for better stability. 

 

The concentration of ammonia nitrogen in the measurement process is easily interfered by potassium ions, so potassium ion compensation is required. The ammonium sensor probe is an integrated sensor that is composed of ammonium ion selective electrode, potassium ion (optional), pH electrode and temperature electrode. 

 

These parameters can mutually correct and compensate the measured value of ammonia nitrogen, and meanwhile achieve the measurement for multiple parameters. The water ammonia sensor is widely used to measure the value of ammonia nitrogen in the nitrification treatment and aeration tanks of the sewage treatment plants, industrial engineering as well as river water.
