Split-type Extractive Particulate Matter Concentration Monitor Product Overview

Product Description

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.

Technical Advantages

True isokinetic sampling, realized by fan and frequency converter control.
The system is equipped with a built-in fan to provide high-temperature back-blowing gas, which can effectively prevent probe contamination, resulting in low maintenance requirements and long maintenance intervals.
Large sampling flow rate, more than ten times that of the conventional extractive heating method, improving the measurement stability under low-concentration soot working conditions.
Rigorous anti-corrosion processes and materials are adopted; there are no rotating parts inside, ensuring a long service life.
