The instrument uses the principle of non-dispersive infrared to detect the concentration of CO and CO2 in the ambient air. It can be used for environmental air monitoring, public places, workplaces, labor protection, civil defense systems, health and epidemic prevention, tunnels, etc. It can also be used for rural environmental air quality monitoring and online monitoring instrument comparison.

This instrument utilizes characteristic absorption spectra in the ultraviolet region for detecting various gases, including ammonia, trimethylamine, hydrogen sulfide, sulfur dioxide, nitric oxide, nitrogen dioxide, ozone, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide, styrene (sulfur-containing and nitrogen-containing malodorous gases), formaldehyde, acetaldehyde, benzaldehyde, acetone, isopentanone (aldehydes and ketones), benzene, toluene, xylene, ethylbenzene (aromatic hydrocarbons), 1,3-butadiene, and isoprene (olefins). Equipped with a high-resolution spectrometer and long-path gas absorption cell, this multi-component gas monitor achieves high resolution and low detection limits. It continuously monitors real-time concentrations of these gases emitted from unorganized sources in industrial and mining enterprises, as well as from working environments and residential spaces, while calculating odor intensity.

This instrument is suitable for emergency detection and concentration exceedance alarms in routine or flammable/explosive environments; toxic and harmful gas detection in occupational health facilities; and can also be used for measuring concentrations of particulate matter (PM1, PM2.5, PM10, TSP) and volatile organic compounds (VOCs) in ambient air. It is applicable for emergency law enforcement monitoring by departments such as environmental protection, health, labor, safety supervision, military, scientific research, and education.

This instrument is a high-precision device designed for detecting odor pollutants in ambient air. It can measure the concentrations of "8+1" odor substances in the standard as well as other malodorous gases, enabling effective monitoring of odor emissions. It supports comprehensive odor pollution monitoring through point, line, area, and emergency assessments.

This integrated flue gas analyzer, developed using the thermal wet method based on UV differential absorption spectroscopy technology, is specifically designed for on-site detection and analysis of pollutant concentrations including SO2, NO, NO2, NH3, CO (electrochemical), CO2 (infrared), and O2 (electrochemical) in emissions from stationary sources. It is particularly suitable for analyzing flue gas components and monitoring ammonia slip emissions in high-humidity environments, including boilers, flues, and industrial kilns with low-concentration emissions.

This instrument uses pitot tube parallel constant velocity sampling method to collect particulate matter
from fixed pollution source exhaust gas, uses β- ray absorption method to detect stack dust concentration, and uses constant potential electrolysis method to detect flue gas concentration. It is suitable for measuring
gas and dust concentration and total emissions of various fixed pollution sources such as boilers, flues, industrial furnaces, etc., as well as detecting equipment dust removal and desulfurization efficiency.

This instrument is applied in fields such as stationary pollution source exhaust gas and greenhouse gas monitoring. Based on Fourier Transform Infrared (FTIR) spectroscopy technology, it can simultaneously analyze and measure various inorganic and organic gases, providing precise quantitative analysis for multiple gases including H₂O, CO₂, CO, SO₂, NO, NO₂, N₂O, NH₃, HCl, CH₄, C₃H₈. Equipped with an infrared spectral absorption database, it can perform qualitative analysis of unknown gases through their absorption spectra.

This instrument employs the Pitot tube parallel isokinetic sampling method to collect particulate matter from exhaust emissions of stationary pollution sources. It uses the filtration and weighing method to determine dust mass, while applying the static potential electrolysis method, UV differential method, or non-dispersive infrared method for qualitative and quantitative analysis of flue gas components. The device is widely used to measure emission concentrations, converted concentrations, total emissions, and dust removal efficiency of particulate matter from various fixed pollution sources including boilers, flues, and industrial furnaces, while also evaluating the dust removal and desulfurization efficiency of equipment.

This instrument operates on the β-ray absorption principle, enabling on-site monitoring of particulate matter concentration in exhaust gases from stationary pollution sources. It provides direct data readings and is unaffected by variations in particle size, shape, or other physicochemical properties. Not only does it offer high measurement accuracy, but it is also lightweight, portable, and features flexible disassembly and assembly, making it particularly suitable for ultra-low emission applications.
