Ultra-Low Oxygen Measurement in Pipes
Oxygen Probe Integrated in Metal Flow-Through Connector FTM-PSt9
An oxygen exchange window for measurement of smallest oxygen traces is integrated in a metal flow-through connector. The FTM-PSt9 is suitable for measurement in gases and has a measurement range of 0 - 200 ppmv oxygen with a detection limit of 0.5 ppmv oxygen. It can be integrated in pipes with o.d. 6 mm or other diameters using the respective adapters. The oxygen probe is very robust and long-term stable.
- Contactless measurements down to 0.5 ppmv oxygen
- No consumption of oxygen
- Polarization free
- Long-term stability
