    • Minimized reagent consumption and waste
    • Reliable results even at very low NH4 concentrations
    • Minimum maintenance
    • Easy to operate
    • Compatible with IQ SENSOR NET

    The Alyza IQ NH4 ammonium analyzer is the latest addition to the IQ SENSOR NET. It can be easily integrated into new and existing systems just as simple as a sensor.
