ZR-7230 Portable Atomic Absorption Mercury Analyzer Introduction: ZR-7230 portable atomic absorption mercury analyzer is a portable equipment for on-site mercury monitoring. The instrument adopts the principle of ultraviolet atomic absorption, and can directly conduct real-time on-site rapid detection of mercury content in the air; It is equipped with a whole process heat tracing sampling smoke gun and a Teflon pipeline flue gas pre processor to avoid water vapor condensation and pipeline adsorption of mercury vapor. It is used to conduct a rapid and accurate on-site detection of mercury in waste gas from fixed pollution sources, so as to avoid sample distortion caused by the lag between on-site sample collection and laboratory analysis. This instrument can meet the requirements for the measurement of mercury content in fixed source waste gas and ambient air, and can be widely used for on-site mercury detection in coal-fired power plants, garbage incineration, chlor alkali production, metal smelting and processing, cement production, crematorium and other industries, as well as on-site emergency monitoring of mercury in ambient air. characteristic: 1. Light source: low pressure mercury lamp capable of producing ultraviolet light with a single wavelength of 253.7nm; 2. The gas circuit and pipeline are made of tetrafluoro and quartz glass to avoid test error caused by pipeline adsorption; 3.
