DP-PSt8-10-L2.5-ST10-YOP
Oxygen Dipping Probe DP-PSt8
- 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
This oxygen probe is used for trace oxygen monitoring in liquids or gasses. It has a stainless steel fitting that covers the end of a polymer optical fiber with an oxygen-sensitive foil attached to it. Protected by this steel housing and with its small outer diameter of 3 mm the sensor can be integrated in liquids and semi-solid samples, such as e. g. sediments or filter sand, without causing disturbance. The probe has a length of 10 cm, but other lengths are also available on request.

A stainless steel tee is equipped with an oxygen microsensor. The FTCM-PSt8 has connectors for 1/16” steel tubing, and an inner volume of only 2.1 µL. It is suited for all applications where only small volumes are available. With a tapered microsensor tip and its extraordinarily fast response time t90 < 3 sec. oxygen monitoring in real time can be performed. The PSt8 type sensor has a measurement range of 0 – 10 % oxygen, with a detection limit of 0.007 % oxygen.

This tiny probe has a tip size of 230 µm. The microsensor tip is not mounted into any additional housing, so it can be applied in various customized applications. The bare glass fiber tip can be mounted to your own housings, steel tubes and micro respirometer chambers etc. The small outer diameter even allows insertion into implantable Venflon-tubes. Moreover the microsensor can be deployed in sealed containers to measure the oxygen content directly. The IMP-PSt8 has a measurement range of 0 – 10 % oxygen, with a limit of detection of 0.007 % O2.

NFSG-PSt8-02-L2.5-TF-NS40/0.8-OIW
Needle-Type Oxygen Microsensor with Fixed Sensor Tip NFSG-PSt8 (Minimum Order Quantity: 3)
- High spatial resolution (< 140 μm)
- High temporal resolution (t90 < 3 sec.)
- No consumption of oxygen
- Signal independent of flow velocity
- Measurement in headspace or smallest volumes
This oxygen sensor is specially designed for headspace measurement in packaging or other applications where gaseous oxygen measurements in small compartments have to be conducted. The tiny sensor tip is fixed inside a steel needle, so it does not protrude the needle tip. Secured inside the needle the sensor can be pierced through material and oxygen traces inside the headspace can be determined within seconds. The NFSG-PSt8 has a measurement range of 0 – 10 % oxygen, with a detection limit of 0.007 % O2.
Specification
NFSG: needle type housing with fixed oxygen microsensor (measurement in gas)

NTH-PSt8-02-L2.5-TF-NS40/0.8-OIW
Needle-Type Oxygen Microsensor NTH-PSt8 (Minimum Order Quantity: 3)
- High spatial resolution (< 230 μm)
- High temporal resolution (t90 < 3 sec.)
- No consumption of oxygen
- Signal independent of flow velocity
- Measures liquids as well as in gas phase
The end of a glass fiber is coated with oxygen-sensitive material with a measurement range of 0 – 10 % oxygen. This tip (230 µm) is protected inside a stainless steel needle and can be extended for measurements. As long as the sensor tip is retracted and protected by the needle the microsensor can be pierced through septum rubber or any other harsh material. With its small tip size and fast response time (t90 < 3 s) this sensor is ideally suited for trace oxygen measurements in research and packaging applications.
