Details
★ Explosion-proof and waterproof design, protection grade IP66, outdoor type, fast detection, reliable and stable;
★ Built-in high-efficiency two-stage condensation dehumidification and dust removal pretreatment system, automatic control integrated design, effectively reduce SO2 loss, prevent water vapor interference, and is more suitable for working conditions with high humidity and low flue gas component concentration;
★ Using differential absorption spectroscopy technology (DOAS), the temperature drift is small, the measurement accuracy is high, and the ultra-low concentration can be measured;
★ Long-life pulsed xenon lamp cold light source, short warm-up time and long service life;
★ Built-in long optical path gas cell, dual range design for NOx and SO2 analysis, automatically switch range control according to the concentration value;
★ The concentration curve of each flue gas component is displayed in real time, and the curve display ratio can be adjusted;
★ Low detection limit, not affected by moisture and dust, strong anti-interference ability, can avoid cross-interference between gases;
★ Built-in heating device, automatically start the heating function at low temperature, so that the analyzer can be used in severe cold areas;
★ Design and develop computer database and communication system software under windows environment to realize computer communication for storage and printing;
★ The fault self-checking function can generate fault reports after detection, which is convenient for users to maintain;
★ Integrated integrated micro thermal printer or external Bluetooth wireless printer;
★ The flue gas conversion method is based on the reference oxygen content conversion method and the conversion factor conversion method;
★ Large-capacity data storage, 16G, can create folders on a daily basis, and store daily test data separately;
★ Optional automatic blowback system;
★ The standard sampling distance is 30-40 meters, and the maximum sampling distance of the optional vacuum pump is more than 70 meters;
★ The flue gas temperature that can be detected and analyzed is the flue gas within 1300 ℃, and the detection and analysis of higher temperature flue gas needs to be customized.
