  • Description
    Digital ISE sensor for ammonium, connectable to the IQ SENSOR NET
    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!
