Ultra-low oxygen measurement in pipes

Metal Flow-Through Cell with Integrated O2 Sensor FTM-PSt9

A sensor stick 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 this metal flow-through cell. The FTM2-PSt9 is suitable for measurement in gases and available with a connector diameter of 1/4". The cell can also be connected to pipes with other diameters using the respective adapters. A polymer optical fiber is screwed to the sensor stick via SMA connector for sensor read-out. The oxygen probe is very robust and long-term stable. The sensor stick can easily be exchanged, if necessary.

  • Perfusion monitoring in gases down to 0.5 ppmv O2
  • No consumption of oxygen
  • Easy exchange of sensor stick
