Product overview

      In recent years, after the release and implementation of national air pollutant emission standards represented by thermal power, steel and other industries, ultra-low emission has become the direction of air pollution control. At present, the widely used monitoring instruments such as non dispersive infrared method and electrochemical method have prominent problems such as high detection limit, component interference and low concentration linearity difference, which can not meet the emission monitoring requirements and environmental management needs of lower concentration, stronger anti-interference ability and more components (SO2, no, NO2, etc.) under the new situation.

      In order to monitor the ultra-low emission of waste gas from fixed pollution sources and obtain representative and accurate monitoring data, it is of great significance to put forward higher requirements for monitoring technology, monitoring instruments and standard methods.

       Asp-3000 portable ultraviolet flue gas analyzer is a low concentration, high-precision and full component monitoring instrument independently developed by 金沙9170登录线路 Co., Ltd. (hereinafter referred to as Nanhuan Technology) after ten years of technology accumulation and precipitation.

application area

       The products can be widely used in waste gas emission monitoring of thermal power generation, steel, metallurgy, petrochemical, cement and other industries, as well as environmental monitoring stations, third-party testing institutions, universities and scientific research institutes.

Asp-3000 portable ultraviolet flue gas analyzer

 

measuring principle

      Asp-3000 portable flue gas analyzer adopts the principle of UV-Vis differential absorption spectrum. The characteristic of this method is that the absorption cross section of gas molecules is divided into two parts: the differential absorption cross section (narrow-band absorption cross section) which changes rapidly with the wavelength caused by the gas molecules to be measured and the wide-band absorption cross section which changes slowly with the wavelength caused by the gas to be measured, interfering gas and dust particles. Through signal processing, the concentration signal of the gas component to be measured can be extracted, and the measured gas concentration can be obtained by using a specific algorithm.

 

 

Product features

The measurement shall not be disturbed by water vapor, Co, CO2 and other components;
