  • 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.
