The Model SDUST-110 Particulate Matter Online Monitoring System consists of a uniquely designed improved heated extraction probe and a high-sensitivity laser small-angle forward-scattering measurement unit, forming an online measurement device suitable for low-concentration particulate matter. It adopts the extractive laser forward-scattering method for measuring low-concentration particulate matter, and is applicable to the measurement of saturated wet flue gas environments such as the outlet after wet desulfurization and the inlet and outlet of wet electrostatic precipitators.

The SDUST-110A Integrated Ultra-Low Particulate Monitor is tailor-made for saturated wet flue gas environments such as the outlets of wet desulfurization systems and the inlets/outlets of wet electrostatic precipitators. It delivers stable and reliable high-precision measurements even under complex operating conditions, providing solid data support for environmental monitoring. Its integrated design not only simplifies the installation process but also, with its efficient and stable performance, meets the stringent requirements of various monitoring sites.

The Model SDUST-100 On-line Dust Monitor is designed for measuring particulate matter concentration in flue gas emissions from stationary pollution sources. It consists of three main parts: the electrical system, optical system, and structural system. This monitor is applicable to the measurement of particulate matter concentration in flue gas emissions from stationary pollution sources across multiple industries, including cement, thermal power, steel, metallurgy, oil refining, aluminum manufacturing, petrochemicals, papermaking, and glass production.

The SLAS-100 Series Tunable Laser Gas Analyzer is a series of analyzers developed for international industrial online analysis and environmental protection online monitoring. This series provides various installation and measurement configurations, including in-situ probe type, bypass type, multi-channel type, and standard 4U rack-mounted type, enabling online analysis of multiple gases—such as O₂, CO, NH₃, CO₂, CH₄, H₂O, HCl, and HF—under various complex working conditions (Note: each analyzer can measure 1–2 components only). The measurable gas concentration ranges from macro levels to trace levels.
