PreSens - Precision Sensing GmbH: Prototype oxygen sensor

A joint project between PreSens Precision Sensing and the Fraunhofer Institute for Process Engineering and Packaging has resulted in the TAF12 sensor for trace oxygen measurement with a low detection limit of 0.5 ppm.

The detection limit in the gas phase of the new, highly-sensitive sensor is said to allow measurements lower by a factor of 50 than in previous systems and has a dynamic range of 0 – 1000 ppm (gas phase). The newly designed measurement cells with improved leak tightness are made of stainless steel.

The new measurement cell with two gas connectors for each of the two chambers; the sensor spot is applied to the upper chamber and read out via polymer optical fiber by the Fibox 3 LCD trace by PreSens.

The new measurement system together with the TAF12 sensor is an easy-to-use and cost-effective method to determine oxygen permeability of important synthetic materials.
