Screening of the nitrate
sensor
The NitraLyt
®
700 IQ nitrate sensor and the NitraLyt combination elec-
trode together with the IQ S

system form a measuring sys-
tem that is protected to a high degree against low and high frequency
interference as well as against the indirect effects of lightning strikes.
1.3 Recommended fields of application
The NitraLyt
®
700 IQ nitrate sensor forms a measuring system for the
online determination of nitrate ions. It supplements the oxygen mea-
surement and/or the ammonium measurement in the aeration tank and
enables an efficient aeration control.
The NitraLyt
®
700 IQ nitrate sensor, together with the NitraLyt nitrate
combination electrode, is suitable for stationary nitrate measurements
in water/wastewater applications.
