Optical D.O. measurement based on dye luminescence is strongly promoted in these days. The manufacturers of such instruments claim far superior performance compared to conventional electrochemical sensors. In theory, the functional principle of the optical D.O. measurement confirms this superiority. However, practical realisation and application does set certain limits and, as usual, further technical development is needed to bring theory and practice to accordance.
WTW's FDO 700 IQ D.O. sensor belongs to a new generation of these sensors that eliminate the drawbacks of the former ones. Its most remarkable features are:
- High accuracy right from the start
- Utmost stability over a long timespan
- Minimum maintenance effort
This is achieved by entirely new technologies:
- Intelligent Membrane with IQMC technology
- Soft Green Light Technology
- (C2) calibrated optics
- EPRS reference procedure

All EV-,ET- and EC-series electronic valves with the "O-" option are available manufactured and assembled for use in Oxygen-enriched environments for applications that are extremely sensitive to contamination.
These valves are ultrasonically cleaned, assembled, inspected and tested in an enclosed controlled area with a state-of-the-art positive pressure filtration system.
Both organic and inorganic contaminants such as particulate matter and hydrocarbon oils are removed.
No organic sealants, adhesive or lubricants are used in the manufacturing process.
Feature FKM (fluorocarbon) seals.
Components parts are lubricated with Oxygen-compatible PFPE (perfluoropolyether) grease, only as needed for assembly.
Individual testing and inspection is accomplished utilizing compressed Nitrogen and ultraviolet light.
Products are double bagged in heat-sealed polyethylene bags. |
