Oxygen Sensor Integrated in Metal Flow-Through Cell FTM-M10-PSt9

Ultra-low oxygen measurements in pipes

Oxygen Sensor Integrated in Metal Flow-Through Cell FTM-M10-PSt9

An Oxygen Exchange Cap (OEC-M10) with PSt9 sensor for measurement of smallest oxygen traces (limit of detection 0.5 ppmv O2, measurement range 0 - 200 ppmv O2) is integrated in a metal flow-through cell via M10 thread. The FTM-M10-PSt9 is suitable for measurement in gases and is available with connector diameters of 6 mm, 1/4" or 1/2". The cells can also be connected to pipes with other diameters using the respective adapters. A polymer optical fiber is inserted in the cap for sensor read-out. For industrial environments robust fibers integrated in a metal spiral tube can be connected to the FTM magnetically. The oxygen probe is very robust and long-term stable. The OEC can easily be exchanged if necessary.

  • Perfusion monitoring down to 0.5 ppmv O2
  • Different FTM sizes available
  • No consumption of oxygen
