New Optical Field D.O. Sensor: FDO® 925

WTW proudly presents the optical field D.O. probe FDO® 925 belonging to the IDS family of intelligent digital sensors.

The FDO® 925 is designed for use with the new MultiLine® digital portable instruments and is suited for field as well as for laboratory use (diameter 0.6” / 15.3 mm). With its extremely fast response (T99 < 60 s) and its bevelled membrane repelling air bubbles, it provides excellent signals for reliable measurements.

The new sensor relies on the technology of WTW’s proven on-line optical D.O. Sensor: Soft green light guarantees a long service life of the optical membrane. The exchangeable membrane cap bears a chip with factory calibration data which are read out by the MultiLine®. In combination with the new digital MultiLine® portable instruments, the new FDO® 925 will re-define mobile D.O. measurement.
