With the development of society and economy, the increase of industrial automation, accompanied by the increasing number of motor vehicles and various industrial enterprises on the road, has led to serious emissions of various harmful gases. The environmental pollution caused by various harmful gases and smog PM2.5 has already appeared very intuitively to everyone, causing great harm to human travel and physical health. Therefore, the governance of the atmospheric environment is urgent.
The hand-held four-in-one gas detector is an intrinsically safe device that can continuously detect the concentration of leaked gas. It is suitable for emergency rescue of gas leaks in various places, underground pipelines or mines, etc., and can effectively ensure that the life safety of workers is not infringed and production equipment is not lost. The detector uses a natural diffusion method to detect the gas, and the sensitive components are imported gas sensors with excellent sensitivity and excellent repeatability. The instrument uses embedded microcomputer control, which is simple to operate, complete in function, high in reliability, and has a variety of adaptive features. Ability; using dot matrix LCD display, intuitive and clear; small and beautiful portable design not only makes you put it down more convenient for your mobile use.

The flue gas continuous monitoring system is controlled by: smoke and dust concentration monitoring subsystem, gaseous pollutant (SO2 / NOX) monitoring subsystem, smoke emission parameters (flue gas temperature, flow, oxygen content, pressure) monitoring subsystem and system control And data acquisition subsystem (DAS). The real-time data of the above monitoring items in the flue gas are measured by sampling, and can be collected, processed, stored and output centrally. The system operation data collection rate will not be less than 95%, and the monitoring data qualification rate will be greater than 90%.
The sampling method of the ammonia escape online monitoring system is in-situ high-temperature heat tracing extraction. The basic principle of this system is based on tunable semiconductor laser absorption light latent (TDLAS) technology: laser spectral gas analysis technology has been widely applied to various gas monitoring fields that have high requirements for sensitivity, response time, and background gas interference-free.
SK-6500 series laser on-line process gas analysis system is based on the international leading semiconductor laser absorption spectroscopy technology (TDLAS), that is, "single-line spectrum" measurement technology. The system uses a tunable semiconductor laser as the light source, and modulates the laser frequency by modulating the operating current intensity of the semiconductor laser to make the laser scanning range slightly larger than the single absorption line of the measured gas. As a result, when a laser beam of a specific wavelength emitted by a semiconductor laser passes through the measuring tube, it is selectively absorbed by the measured gas, thereby causing attenuation of the laser intensity. Therefore, the system uses the Beer-Lambert relationship between different gas components with different characteristic absorption lines and the gas concentration and the infrared or laser absorption spectrum. It can be obtained by detecting the absorption size of the absorption line (that is, the laser intensity attenuation information). The concentration of the measured gas. But the difference is that the traditional non-spectral infrared analysis technology uses an infrared light source with a wide spectral width and a fixed wavelength, while the DLAS technology uses a semiconductor laser with a very small spectral width (that is, very good monochromaticity) and a tunable wavelength as the light source. Therefore, TDLAS technology has some performance advantages that traditional non-spectral infrared analysis technology cannot achieve.
