Ultra-low oxygen measurements with metal flow-through cells
Oxygen Exchange Cap OEC-M10-PSt9
This oxygen exchange cap holds a PSt9 oxygen sensor (measurement range 0 - 200 ppmv O2, limit of detection 0.5 ppmv O2) for measurements of ultra-low oxygen traces in gas pipes. The OEC-M10 can be screwed to a FTM-M10 via its M10 thread. This way a used sensor coating in your flow-through cell can easily be replaced. A polymer optical fiber with protective metal spiral tube cover can be attached to this OEC. The PSt9 sensor is only suitable for measurements in the gas phase.
- Replacement sensor for FTM-M10
- Detect ultra-low oxygen traces in gas pipelines
- Max. measurement range 0 - 200 ppmv O2, limit of detection 0.5 ppmv O2
- Signal independent from flow velocity
