Product Introduction

The product complies with HJ XXX-201X Technical and Detection Methods for Portable Sulfur Dioxide and Nitrogen Oxides Optical Measurement Instruments (Draft for Comments); JJG986-2002 Verification Regulation for Flue Gas Analyzers; Enterprise standard Q/WTH39-2017 TH-890C Portable Infrared Flue Gas Analyzer.

Application Scope

This unit can preprocess high-temperature sample gas, effectively removing smoke dust, acid mist, and aerosols from the sample gas, and selectively removing gaseous moisture while largely retaining the gaseous pollutants to be detected. The instrument features short preheating time, simple operation, portability, and excellent dehumidification effect. It is mainly used for flue gas sampling preprocessing in heavy and highly polluting industries such as thermal power, chemical, electronics, steel, etc., as well as various complex working condition flues. It provides reliable assurance for accurate measurement by flue gas analyzers under ultra-low emission conditions.

Instrument Features

Dust Removal: External and internal filters can remove particles smaller than 1 micron from the sample gas;

Ammonia Removal: Built-in ammonia filter inside the unit removes ammonia that may damage the drying tube through periodically replaceable ammonia removal packing, extending equipment service life;

Water Removal: Through two different models of built-in Nafion drying tubes, combined with dynamic heating and purge gas system, to achieve removal of gaseous moisture while completely retaining gaseous pollutants;

Nafion Drying Tube Technology: Uses internationally advanced Nafion drying tube dehumidification technology, effectively removing water molecules while retaining the target gases;

Full-Path Companion Heating: Heating and insulation from sampling to the inlet end of the internal drying tube, full-path no-dead-zone heating and constant temperature to prevent condensation anywhere;

Large Screen Display: 6.5-inch large color touch display screen, simple and convenient operation.
