Online Ammonia Nitrogen Sensor RS485 Modbus PLC DCS

1.Application Environment

KAN310 integrated on-line ammonia-nitrogen sensor is made of ammonium ion selective electrode based on PVC membrane, which is used to measure the content of ammonium ion in water with temperature compensation.

2.Feature

• Signal Output: RS-485 bus, Modbus/RTU protocol,
• Convenient to connect to PLC, DCS, Industrial Control Computer, General Controller, paperless recording instrument or touch screen and other third-party equipment.
• The patented ammonium ion probe, with an internal reference fluid at a pressure of at least 100 kpa (1 bar), oozes extremely slowly from the microporous salt bridge. Such a reference system is very stable and the electrode life is longer than ordinary industrial electrode life.
• Easy to install: submerged installation.
• Ip68, containment level.

Tip: Do you know these methods for determining ammonia nitrogen?

Nessler's reagent spectrophotometry:

The alkaline solution of mercury iodide and potassium iodide reacts with ammonia to form a reddish-brown colloidal compound whose color is proportional to the content of ammonia nitrogen. The absorbance can usually be measured in the wavelength range of 410~425nm to calculate its content.

The lowest detectable concentration of this method is 0.025mg/L (photometric method), and the upper limit of determination is 2mg/L. Using visual colorimetry, the lowest detectable concentration is 0.02mg/L. After proper pretreatment of the water sample, The method can be used for the determination of ammonia nitrogen in surface water, groundwater, industrial wastewater, and domestic sewage.
