Robust Probe for Measurement of Smallest Oxygen Traces
Oxygen Dipping Probe DP-PSt9
This oxygen dipping probe is used to measure ultra-low oxygen traces in gasses. It is made of a polymer optical fiber with the oxygen-sensitive sensor attached to one end. In order to protect both – the fiber and the sensor – the fiber end is covered with a high grade steel tube. The dipping probe has an outer diameter of 4 mm and a length of 10 cm. Other lengths are available on request.
- Excellent long-term stability
- Pressure resistant (max. 5 bar)
- Polarization-free
- No membrane clenaing and replacement necessary
- No electrolyte solution to replenish
- Long shelf life
