Sewerin gas detection instruments are used to identify and quantify gas leaks in natural gas distribution networks. Designed to be intuitive to use for many different tasks in the gas utility industry the infrared sensors ensure accuracy and sensitivity. Our equipment is used in many countries by all the world`s major gas supply companies.
Axetris infrared sources are used in a variety of industrial applications: Combustible and Toxic Gas Detection, Refrigerant Monitoring, SF6 Monitoring, Fruit Ripening Monitoring, Flame Detection, Liquid Analysis using Attenuated Total Reflection ATR, Semiconductor Fabrication.
Ensuring reliable and accurate carbon dioxide measurement. With accurate and reliable carbon dioxide monitoring being an important part of horticultural climate control, Edinburgh Sensor’s Guardian range includes dual wavelength non-dispersive infrared sensor technology with built-in temperature correction. This ensures reliable and accurate carbon dioxide measurement together with long term stability.
Most large coal fired power plants and combustion processes are required to monitor CO, NO and NO2 (NOx), SO2 and possibly CO2; in addition the analyser has to be normalised to Standard conditions. For this application CODEL offers the five channel GCEM 40 series which uses Infrared absorption to measure these gases plus moisture, pressure and temperature. The analyser can be configured for single channel operation to monitor any of these gases plus CH4 and HCl.
In a complex petrochemical facility there may be many thousands of potential leaks paths. Some may be leaking but most will not. Using an infrared Gas Detection camera allows the user to examine many potential leaks sources in a short time and from a distance. The EPA acknowledged gas imaging cameras, such as Opgal’s EyeCGas®, as an approved Leak Detection and Repair (LDAR) Method 21 alternate work practice (AWP).
“Biogas” means a mixture of various types of gas (mostly methane) produced by bacterial fermentation in anaerobic conditions(absence of oxygen) of organic residues from waste, decaying plant, carcasses in putrescence. The analyzers of biogas by Infrared cells carry out the continuous analysis of CH4, O2, CO2, H2S and NH3. The whole process sees the decomposition of organic material by some types of bacteria, producing carbon dioxide, molecular hydrogen and methane(methane conversion of organic compounds...
Comparison of TechnologiesA gas chromatograph (GC) has traditionally been the technology of choice for laboratory analysis of gas samples. GCs have been used for over 50 years in the qualification and quantification of complex mixtures of gases. The techniques and methodology required to run GCs are often a pre-requisite for any laboratory technician. Recent developments in Fourier Transform Infra-Red (FTIR) gas analysis has enabled this technology to start to replace GCs in the lab.
The TunnelTech 200 series are primarily gas monitors with optional Visibility capability. Most use Infra-red absorption technology to monitor gaseous pollutants and those with a visibility channel use optical attenuation for that application. All TunnelTech 200 analysers except the TunnelTech 205 use the same rugged corrosion resistant enclosures and have an optional Data Display unit. As there is only one moving part so reliability levels are very high and maintenance levels very low.
