Gas Test Bench

The gas test bench aims to characterize the sensitivity of gas sensors designed for environmental applications. It is particularly used to test gas sensors installed in the instrumented composting fountain (https://fde.umontpellier.fr/2023/composteur/).

The test bench enables the creation of gas mixtures (Air, CO₂, CH₄: 10 to 5000 ppm) within a sealed chamber equipped with 8 leak-proof BNC outputs. A control and data acquisition system complements the test bench.

  • The mass flow controllers (MFCs) included in the bench are:MFC Air 4L/min
  • MFC CH4 40mL/min
  • MFC CO2 40mL/min
