IISE sensor for ammonium - WTW Germany

Ammonium measurement directly in the medium without sample preparation and sample transfer. Measurement of centrate and other process waters up to 2,000 mg/l NH4-N:

• Calibration free, long-term stability
• No chemicals
• Short response times

The ISE sensor AmmoLyt®Plus 700 IQ allows ammonium measurement directly in the process. Time-consuming steps such as sampling and preparation are eliminated. For stable measured values, the interference substance potassium is compensated simultaneously and can be displayed if needed. An energy-optimized operation by a suitable regulation of the blower aggregates is made possible by this ISE sensor. This will help effectively reduce operating costs of the system, which is amortized by the system in a very short time. Starting now, you will be able to reliably determine centrate and other process water with high ammonium load up to 2.000 mg/l NH4-N with the AmmoLyt®Plus!
