紫外doas Gas分析仪so2，无范围测量

Feature:

• UV spectroscopy technology and differential absorption spectroscopy algorithm are the most accurate online analysis method for SO2, NO and other gases. Compared with the non-spectroscopic infrared analyzer, it has the advantages of no cross-interference, not affected by dust and water, small temperature drift and so on；
• The absorption strength of the gas in different bands is different, and the automatic measuring range switching is far larger than the non-spectroscopic infrared technology and the non-spectroscopic ultraviolet technology；
• The analyzer gas chamber is made of stainless steel or anti-corrosion aluminum, without mirror polishing and gilt copper plating. The gas chamber has low cost and convenient maintenance；
• The ultra-low analyzer gas chamber adopts multiple turn-back technology, with an effective light range of more than 1 meter and a resolution of less than 1 mg/m3, realizing the ultra-low measurement of real significance.
• The gas chamber has its own high temperature heating function, which is very suitable for measurement in high humidity environment；
• Optical fiber connection is used between the light source, measuring room andspectrometer, with no moving parts, good reliability, convenient installation andmaintenance, and the site vibration does not affect the measurement results；
• Adopting pulsed xenon lamp light source with life time is more than five years, which is a cold light source, compared with the infrared light source, it has with the advantages of long life, no preheating time, good stability；
• NO and NO2 have strong absorption in the ultraviolet band, and they can accumulate NO x by simultaneously measuring N O and NO2, saving customers on the cost of NOx converter；
• Gas chamber, light source, spectrometer, etc., are modular design, easy disassembly, and easy to expand with CO and CO2 sensors；
• Daily automatically correction for higher reliability of the measurement data；
• It has automatic alarm and recording function under abnormal failure, power failure and excessive detection data；
• Touch screen for easy operation & friendly interface.
