Digital, optical, calibration free – dissolved oxygen senors for the IQ SENSOR NET
Calibration-free, reliable, DIN compliant – the optical FDO® oxygen sensors for the IQ SENSOR NET to regulate biological cleaning steps:
• Calibration and flow free
• Insensitive to air bubbles
• Low usage costs
FDO® sensors are the perfect solution for measuring dissolved oxygen. In addition to being free of calibration and flow, with their 45° membrane, they are also insensitive to air bubbles. Therefore, you will not require any additional installation equipment. The robust design of this sensors allows the use with an overpressure of up to 10 bar. The special membrane has a unique stability and thus ensures stable measured values.
The sea water model (FDO® 700 IQ SW) is optimized for use in special media: All wetted parts are made of titanium and plastic and are therefore extremely resistant to corrosion.
