      Axetris公司應用了具有專利的信號增強類TDLS技術來檢測氣體濃度,使用了極窄的0.05nm的激光束來掃描目標氣體吸收波段的方法,類似一種高分辨率的近紅外光譜吸收測量。

      激光氣體檢測模塊,基于可調諧二極管激光光譜技術(TDLS),為在環境氣體檢測及過程控制應用中許多難以檢測的氣體提供了有價值的解決方案。

      • TDLS 技術提供以下獨特的技術優勢:

      • 光學式,非接觸式,精準激光測量

      • 極高的目標氣體選擇性

      • 能檢測低于ppm級別檢測限的氣體,如CH4,NH3,HCl,H2O,CO2

      • 低成本

      • 具有很高的穩定性,可靠性,有效性(無需定期替換備件/標定)

      我司的激光氣體檢測模塊,為OEM 集成商提供了一個高性價的解決方案,可應用于氣體排放控制和環境監測?;诜浅*毩⑹降哪K設計,客戶可簡便地將之集成在系統中。我司也提供高溫型氣體檢測模塊(氣室加熱到220 ℃),它特別適用于具有高污染性樣氣的檢測,比如SCR脫硝中(DeNOx)及其它一些工業氣體檢測的應用。我司的激光氣體檢測模塊, 可實現多種氣體監控及檢測的應用,例如燃燒控制,泄漏檢測,呼吸氣體分析,溫室氣體排放監測及安全監測等許多應用。




      Laser Gas Detection TDLS Technology 【English】

      Leister Corporate, Axetris, Laser Gas Detector 

      Axetris uses proprietary technology-enhanced TDLS for gas detection. A 0.05 nm narrow bandwidth diode laser beam is used to scan across an absorption band of the target gas, thus performing a high-resolution near infrared absorption measurement. 

      Laser gas detection, based on Tunable Diode Laser Spectroscopy or TDLS, provides a valid solution to many challenges in environmental gas monitoring and process control. 

      The TDLS technology offers unique advantages like:


      • precise optical, contactless measurements

      • excellent target gas selectivity

      • sub ppm-level detectivity for gases such as CH4, NH3, HCl, H2O and CO2

      • low cost of ownership

      • high stability, reliability and availability in the field (no regular replacements / calibration needed)


      Our laser gas sensing modules are a cost effective solution for OEM integrators active in emission control and environmental monitoring. It allows for simple integration due to its self-contained and standalone system design. It also offers hot-gas measurements up to 220°C, which provide a robust sensing solution for highly contaminated gas sample typically for SCR DeNOx and other industrial applications. With our gas sensing modules, we are able to cover a wide range of gas monitoring & detection applications in combustion control, leak detection, breath gas analysis, greenhouse gas monitoring, safety and many more.
