WTW Optical IQ sensors for dissolved oxygen

Optical FDO® oxygen sensors

for the IQ Sensor Net to regulate biological cleaning steps – calibration-free, reliable, DIN compliant:

• 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.
