　　 1Handheld ship exhaust analyzer UV portable smoke analyzerIntroduction

　　Handheld ship exhaust analyzer UV portable smoke analyzer is a handheld analytical instrument used for rapid detection of ship exhaust. Using the fast principle of DOAS ultraviolet differential absorption spectroscopy, the gas components such as SO2/NO/NOX in ship exhaust are measured by thermal wet method, and the gas components such as O2/CO/CO2/H2S are measured by fixed potential electrolysis method, which is particularly suitable for measuring harmful gas components in high CO, high humidity, low SO2, and ship exhaust.

　　The instrument can be used for on-site ship exhaust gas detection and law enforcement, with advantages such as high measurement accuracy, strong reliability, fast response time, and long service life. The on-site humidity of the instrument is high, especially the interference caused by high concentration of dioxide. Conventional instruments cannot detect the concentration of dioxide, so this instrument can be used.

　　With the continuous increase in the number of ocean (inland) transport ships, the pollution caused by the emission of ship exhaust to the atmosphere and water bodies is becoming increasingly serious. The exhaust emissions from ship internal combustion engines are mainly composed of dioxide and nitrogen oxides. According to the International Maritime Organization, a series of ship pollution prevention conventions have been formulated to limit the emission of ship exhaust and regulate the use of fuel, strengthening the protection of the atmospheric and marine ecological environment. The online monitoring system for ship exhaust plays an important role in pollutant treatment, providing means and basis for exhaust treatment and environmental management.

　　The integrated structure of the dust filtering heating sampling tube and the host effectively reduces the adsorption of SO2 by condensed water in the pipeline, improves measurement accuracy, and has a 5.0-inch wide temperature color touch screen with a touch screen

　　The ultraviolet differential absorption spectroscopy (DOAS) method is currently the analytical tool for gases such as SO2, NO, NO2, NH3, etc. The hot and wet methods directly measure SO2, NO, NO2 in flue gas, and the measurement accuracy is completely unaffected by moisture and dust. It is particularly suitable for high CO, high humidity, low SO2, and ship exhaust, and has the advantages of low detection limit and small temperature drift

　　Mold based optical path design improves instrument stability and reduces the impact of environmental temperature changes on monitoring results
