Sulfur dioxide analyser AM501

monitoringfor ambient airfor wastewater

This AM501 Sulfur Dioxide Analyser uses the Ultraviolet Fluorescence Method and allows accurate, dependable, continuous measurements for ambient air quality, stack gas monitoring, and other applications. It consists of an optical sensor module, an analog signal pre-processing module, a microprocessor controller, and a gas circuit module. Applications > Environmental air quality monitoring > Mobile monitoring vehicles > Fugitive emissions monitoring for factories such as petrochemical plants, waste incineration plants, and wastewater treatment plants > Dilution type continuous emission monitoring system for flue gas Technical Features > Periodic monitor of the fluorescence background signal by sampling zero gas to mitigate zero drift > Automatic temperature and pressure compensation > Detection of low concentrations of sulfur dioxide at ppb level with excellent dynamic range and linearity > Two measuring ranges can be set with an automatic switching function
