WTW SensoLyt 700 IQ

FDO 700/701 IQ

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.

FDO® sensors are the perfect solution for measuring dissolved oxygen. In addition to being free of calibration and flow, with their replaceable 45° membrane cap. Therefore, you will not require any additional installation equipment. The robust design of this sensors allows the use with an over-pressure of up to 10 bar. The special membrane has a unique stability and thus ensures stable measured values.

FDO 701 IQ is just like the 700 however it offers a faster response time. Both the 700 and 701 have a sea water (SW) version. 

The sea water model (FDO® 700 IQ SW) is optimised for use in special media: All wetted parts are made of titanium and plastic and are therefore extremely resistant to corrosion
