• High Throughut Glass Fiber Membrane Cobetter Glass Fiber membrane is made of hydrophobic glass fiber, it has good adsorption of particles in ambient air. The retention efficiency of 0.3μm standard particles can reach 99.99%.
  • 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.
