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.
