  • Description

    Digital ISE sensor for nitrate, connectable to the IQ SENSOR NET

    Nitrogen elimination – transparent, process optimized, economical. Nitrate measurement directly in the medium - optimized for regulation purposes:

    • Chloride compensation (optional)
    • Calibration free, long-term stability
    • Economical & cost efficient

    With the NitraLyt®Plus 700 IQ, nitrate can be determined directly in the medium. This makes measured values available in a timely manner and they can easily be used for regulation purposes. Another plus of the IQ SENSOR NET probe is the low investment and maintenance cost.
