MultiGas Ultraviolet Module NDUV / UVRAS

Overview

SO₂ NO₂ NO

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).

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 NO_x converter required
Compact size
In »Thermobox« as standard for stable measurement conditions

Recalibration

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.
