Optical IDS dissolved oxygen sensors with universal plug head – digital & wireless ready

WTW sensors digital optical dissolved oxygen sensor (IDS) with plug head FDO® 925-P

FDO® 925 – optical oxygen sensors for applications in the lab and process, field and wastewater treatment systems - low-maintenance, quick and wireless

  • Saves time and money – low-maintenance & quick (t99 < 60s)
  • Flow-free with beveled membrane
  • Factory calibrated sensor cap with smart chip

The FDO® 925 is especially suited for lab and process thanks to its compact size. The flow-free, easy to clean beveled membrane allows it to be used in containers with low sample volumes. Also, low oxygen concentrations below 1 mg/l can be shown exactly.

WTW's proven FDO® 925 is now available as sustainable plug head version. The universal plug head fits the sensor with wireless functionality – disturbing cables are no longer required.
Furthermore it can be connected to AS/IDS-x cables with lengths of up to 100 m. With this new technology WTW significantly expands the range of applications and the measuring comfort of its optical dissolved oxygen sensors.
