MultiGas Ultraviolet Module NDUV / UVRAS

Overview NO / NO2 / SO2 / H2S For the detection of NO and H2S an EDL (electrodeless gas discharge lamp) is used. A combination of both technologies (UVRAS & …



NO का पता लगाने के लिए एक EDL (इलेक्ट्रोडलेस गैस डिस्चार्ज लैंप) का उपयोग किया जाता है। EDL में, N2 और O2 NO में परिवर्तित हो जाते हैं और चयनात्मक UV विकिरण उत्पन्न करते हैं। इस विकिरण के साथ एक क्रॉस सेंसिटिविटी मुक्त NO माप संभव है। इस विधि को यूवी अनुनाद स्पेक्ट्रोस्कोपी (यूवीआरएएस) कहा जाता है।

A combination of both technologies (UVRAS & NDUV) allows simultaneous gas analysis of NO, NO2 and SO2 in the lower ppm range, which is particularly important in flue gas analysis (CEM, Continuous Emission Monitoring).

  • पोर्टेबल गैस विश्लेषण (PEMS, पोर्टेबल एमिशन मॉनिटरिंग सिस्टम)

Characteristics and Benefits

  • Group of detectable gases:
    SO2 NO2 NO
  • Temperature controlled up to 55 °C
  • Fast response time < 3 seconds
  • Durable EDL (> 16000 h)
  • Flow-independent measurement 0-2 L/min
  • No influence of gas humidity
  • No NOx converter required
  • Compact size
  • In »Thermobox« as standard for stable measurement conditions


  • Readjustment of the zero-point is recommended once a week.
  • Contamination of the measuring cuvette can lead to shifting of the end-point. Due to the integrated filter, re-adjustment of the end-point is generally not required – but can be performed once a year.
  • Additionally, cartridges filled with an inert and the respective test gas for recalibration of the zero and end-point can be provided.
  • Long-term drift is < 1% of Full Scale (F.S.) / 24 h.
