Exhaled Breath = 78.04% Nitrogen + 13.6%-16% Oxygen = CO2 Car Exhaust = Carbon Dioxide + Carbon Monoxide + Sulphur Dioxide + Nitrogen Oxides + Hydrocarbons How do we know this? Gas detection in Continuous Emission Systems (CEMS), combustion analysers and environmental monitoring are key to ensuring that the world we live in is monitored for its pollution and environments we work in are safe to do so as gases can be detrimental to life. Knight Optical provide a number of optical components that are used in Gas Detection Systems. We can also provide interference bandpass filters that work within the IR, front surface mirrors, gas cells and singlet lenses and window made from Germanium (Ge), Calcium Fluoride (CaF2), Silicon (Si), Quartz/ Fused Silica, Magnesium Fluoride (MgF2) and Sapphire (Al2O3).

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

Utilities personnel working on Gas Insulated Switchgear are in danger from exposure to SF6 gas leaks. Colourless and odourless, SF6 can accumulate undetected, presenting serious health and environmental risk. The EMT GasSafe Gas Leak Detection System offers a feature packed solution to monitoring real time gas leaks from electrical equipment or potential other unsafe gaseous emissions. Our gas safety system provides rapid detection, immediate response and early warning in the event of gas leaks or an unsafe working environment, ensuring personnel safety and asset protection. Ideal for traditional SF6 and new SF6 alternative gas installations. Provides an intelligent and comprehensive solution to your SF6 F-Gas leak detection requirements. Measurement of over 400 different gases and vapours from ppm to %Vol. Easily add or remove sensors and accessories as your system needs grow with up to 128 detectors on a single control panel.

The Fire Thermal Infrared (FireTIR) detection system is based on fixed infrared cameras which measure the viewed surface temperatures in real time and connect to a user friendly software interface.
