Gas Detection Systems use Interference Bandpass Filters to identify the emission of a type of gas. Different gases emit at a specific wavelength which makes it identifiable when using a relevant Interference Bandpass Filter. These wavelengths are: Carbon Monoxide (CO) @ 4.73μm Nitric Oxide (NO) @ 5.24μm Nitrogen Dioxide (NO₂) @ 6.17μm Sulphur Dioxide (SO₂) @ 7.42μm Hydrogen Chloride (HCl) @ 3.55μm Carbon Dioxide (CO₂) @ 10.7μm Knight Optical provide a wide range of interference bandpass filters that can be used with gas detection. The Interference Bandpass Filters would be need to transmit in the infrared region. These would be a customised item, which we are very experienced in. We provide narrow, standard, broadband and extra broadband filters with a high optical density of 4 as standard, however this can be customised for you. For more information read PDF

Minimize false readings or premature degradation Gas-absorbing filters from Porex target specific gases that may cause a sensor to have a false reading or cause premature degradation of the cell itself. Specifically designed for your sensor devices, our gas-absorbing filters: Are effective at capturing a wide range of gases that can be harmful to your sensor, including H 2S, SO 2, HMDS, organics, alcohols and many others. Absorb larger amounts of the problem gas –Compared to competitive materials, POREX® filters absorb more problem gas per unit volume, lasting longer than competitive products. Contain safe materials–POREX filters are constructed with safe-to-use reagents, unlike competitive products with toxic lead-containing components.
