PTFE membrane laminated onto a PET support

Cobetter ePTFE protective membrane is suitable for automatic monitoring device for CO, SO2, NO2, NOx, O3, ect. It can delect liquid or spray water, big particles and dust of ambient air, in the meantime, it won’t adsorb detected gas so that can protect equipment, reduce maintain cost and assure the accuracy of result.

  • High particle loading, good dust filtration ability
  • Hydrophobic membrane, stop liquid and spray water
  • Low chemical background
  • No adsorption of detected gas
  • Easy to use, 180℃ thermostability
