Oxygen & Temperature Flow-Through Cell


  • With contactless oxygen & temp sensor
  • For ca. 3.2 or 4.0 mm ID tubings
  • Recommended flow rate: 20-500 mL/min
  • Measurement range temp 0°C - 50°C
  • True temperature compensation possible

This combined flow-through cell has an integrated optical temperature and oxygen sensor for contactless measurements in gaseous or liquid samples flowing through the cell. The cell is equipped with Luer-lock connectors on both tubing ends. The included set of Luer-lock adapters allows direct connection of tubings with ca. 3-4 mm inner diameter. The optical temperature sensor in the combined flow-through cell can be used for true temperature compensation of the integrated oxygen sensor for high precision measurements.

Standard range. This sensor is specified for an optimum measuring range of 0 to 500 hPa oxygen (0 -250% air saturation). However, without specifications, it is possible to measure in up to 1 bar pure oxygen/100% oxygen saturation/100% O2. For detailed specifications, see the respective pdf file in the Downloads tab.

Temperature range. This sensor is specified for the range of 0 to 50°C. Measurements at higher temperatures are possible, but the sensor specifications are not valid for temperatures out of this range.

Optical Fiber


  • For contactless sensor readout
  • Optical fiber core Ø = 1mm
  • Ca. 1m length
  • With ST-connector and bare fiber end
  • To measure through 0-2mm thick materials

0% O2 Calibration Capsules 


For recommended 0% O2 calibration of optical oxygen sensors. Each capsule results in 50mL calibration solution (PU=10).

Every PyroScience multi-analyte (oxygen + temp) meter is generally compatible to this sensor. However, we recommend a multi channel device. This way all sensors can be read out simultaneously. Pay attention to the correct optical fiber for contactless readout. All options can be found under accessories for contactless readout. Use the link below to get a list of all compatible meters.
