    The instrument uses the parallel-speed isochronous sampling method of the pitot tube to collect the particulate matter in the exhaust gas of the fixed pollution source, measures the dust quality by the filtration weighing method, and quantitatively measures the smoke component by the fixed potential electrolysis. It can be applied to the determination of emission concentration, conversion concentration, total discharge of fixed pollutants such as boilers, flue, industrial furnaces and kiln, and the determination of equipment dust removal and desulfurization efficiency; automatic measurement of smoke pneumatic pressure, smoke static pressure, flow rate , pre-flowmeter pressure, flowmeter temperature, flue gas temperature, moisture content, O ₂ , SO ₂ , CO, NO, NO ₂ , H ₂ S, CO ₂ concentration and other parameters.

This instrument is an indispensable instrument carefully developed by our company for collecting pollution sources or samples of harmful gases in the atmosphere. During the development process, the opinions of experts and users were extensively consulted, and the high-tech in the fields of computers, sensors and new materials was applied, which made the sampler small and portable, stable in flow rate and long in service life, which greatly reduced the labor intensity of the samplers.

Based on the principle of ultraviolet photometry, the instrument adopts LED light source and long-path absorption chamber to achieve high-precision determination of ozone in ambient air. The product has the characteristics of small size, light weight, no need for preheating, low detection limit, high sensitivity and fast response. At the same time, it integrates the Internet of Things and cloud platform technology to realize remote real-time data transmission monitoring. It is a kind of ambient air. Portable instrument for instantaneous determination and continuous automatic monitoring of ozone.

The instrument uses a filter weighing method to capture total suspended particulates (TSP) or inhalable particulates (PM10) or fine particulate matter (PM2.5 optional) in ambient air. The new upgrade of the three core systems ensures the reliability of the instrument, improves the stability of the system, and enhances the accuracy of control. It can be used in environmental protection, health, labor, safety supervision, military, scientific research, education and other departments for aerosols. Regular monitoring.

The instrument uses filter membrane weighing method to capture total suspended particulates (TSP) and inhalable particulates (PM 10 ) or fine particulate matter (PM 2.5 optional) in the ambient atmosphere; the ambient atmosphere and indoor air are collected by solution absorption method. A must-have instrument for polluting gas components (SO ₂ , NO _{X ,}  etc.). It can be used for environmental or health, labor, safety, military, scientific research, education and other departments for routine or emergency monitoring of particulate matter, gaseous substances and aerosols.

The instrument adopts the air bag method to collect non-methane total hydrocarbons and some VOCs and other volatile organic compounds in the fixed pollution source exhaust gas with a temperature lower than 150 °C.

The instrument is suitable for manually collecting non-methane total hydrocarbons and some VOCs in fixed pollution source exhaust gas with temperature below 150 °C using fluoropolymer film air bag such as polyvinyl fluoride (PVF).

The instrument uses passive sampling to collect a variety of gases, especially for the sampling of volatile organic compounds. It has the advantages of simple operation and good sealing performance. Compared with traditional gas samplers, the monitoring efficiency and quality of volatile organic compounds are improved. It can be used for environmental and health, labor, security, military, scientific research, education and other departments for the collection of various sample gases.

This instrument is a multi-function instrument that takes into account the sampling of dust pollutants such as fluoride, heavy metals, TSP, PM10 and PM2.5 in ambient air. The flow rate of the sampling working point of the instrument covers 16.7L/min, 50.0L/min and 100.0L/min. When the flow rate is 50.0L/min and the flow rate is 100.0L/min, the load capacity can reach 20kPa, which can realize multi-purpose of one machine.

The instrument is designed according to HJ77.2-2008 "Isotope Diluted High Resolution Gas Chromatography-High Resolution Mass Spectrometry for Ambient Air and Exhaust Dioxins", and the new three core systems are upgraded to ensure the reliability of the instrument and improve the performance. The stability of the system and the accuracy of the control are mainly applied to the dioxin sampling in the ambient environment of the ambient air, waste incineration power plant area and other environmental air containing POPs and floating dust.
