FDO700 IQ sensors for dissolved oxygen
Calibration-free, reliable, DIN compliant – the optical FDO® oxygen sensors for the IQ SENSOR NET to regulate biological cleaning steps
IQ optical spectral probes (UV-VIS) for carbon parameters and suspended solids
Optimal for the measurement of TOC and DOC in the inlet/effluent of municipal wastewater treatment plants.
Thanks to its innovative optics and spectral measuring technique, this is sensor is calibration-free. An optimized referencing ensures an excellent zero point and long-term stability. This ensures reliable measuring results! The maintenance-free WTW ultrasonic cleaning technology reduces the manual cleaning effort to a minimum.
