Non-invasive Measurement of Smallest Oxygen Traces
Ultra-Trace Oxygen Sensor Spot SP-PSt9
The SP-PSt9 have been designed for measurements of even smallest gaseous oxygen traces. These sensors are especially suited for material research or oxygen sensitive technical applications. The contactless read-out of the sensors allows to place them in closed chambers or systems, while measurements can be taken through an optical window. The SP-PSt9 have a measurement range of 0 – 200 ppmv oxygen, and a detection limit of 0.5 ppmv oxygen. These oxygen sensor spots are suitable for gaseous oxygen measurements only.
- Contactless measurements down to 0.5 ppmv oxygen
- No consumption of oxygen
