Ultra low dust monitoring system

　　1、 Product Introduction

The SDUST-110 particulate matter online monitoring system combines laser analysis technology with Chinese environmental monitoring technology. It uses a uniquely designed improved heating extraction probe and a high-sensitivity laser small angle forward scattering laser measurement unit to form an online measurement device suitable for low concentration particulate matter (with main ranges of 0-10mg/m3 and 0-30mg/m3). This device is based on relevant standards and specifications such as HJ 75-2017, HJ 76-2017, JJG846-2015, and uses the extraction laser forward scattering method to measure low concentration particulate matter. Suitable for measuring saturated wet flue gas environments such as the outlet after wet desulfurization and the inlet and outlet of wet electrostatic precipitators.

　　2、 Product Features

　　● True constant velocity sampling is achieved through the control of fans and frequency converters;

● Passed HJ76-2017 version certification;

● High temperature laser forward scattering principle; High precision and minimal maintenance;

Extraction heating method, which does not change the composition of the flue gas;

The system comes with a fan that provides high-temperature back blowing air, which can effectively prevent probe contamination. It requires minimal maintenance and has a long maintenance interval;

● Optional automatic range switching function;

The probe and measurement unit are integrated together, with a compact design and a short sample gas transmission route;

　　3、 Technical advantages

● Integrated design, easy installation;

The sampling flow rate is large, more than ten times that of the conventional extraction heating method, which increases the stability of low concentration smoke and dust measurement conditions;

Online continuous measurement with minimal maintenance;

High sensitivity, measurement error less than 1mg/m3, measurement accuracy of 0.1mg/m3;

● Easy installation, single-sided installation of the flue;

Long working life, with no rotating parts inside;

Strict anti-corrosion processes and materials.
