Concentration monitoring system 909

gasair(CEMS) continuous emission

The 909 is a single gas continuous emissions monitoring (CEM) system that measures stack effluent temperature and velocity alongside pollutant concentrations at stack conditions. This enables mass emission rates to be reported. With no moving parts, the 909 offers high reliability and reduced maintenance requirements. It provides sample and mass flow measurements in one device, with an optional zirconium oxide sensor for oxygen measurement. The sample cell and all components in contact with the sample are heated above the dew points of all gases in the sample stream. This gives a more accurate calculation of gas concentrations, compared to CEM systems that require water removal or sample dilution. Designed specifically for stack emission monitoring in sulfur recovery incinerators and sulfuric acid plants, the 909 is ideal for applications in the hydrocarbon processing industry. FULL-FUNCTION CEM The 909 performs all necessary sample gas and calibration flow management tasks, as well as probe and sample line temperature control. Only a sample probe and sample line are required for full operation. DURABLE DESIGN Designed to operate without moving parts, the 909 is built for maximum reliability and durability. It is a complete system with a sample extraction and transport system designed to ensure sample integrity. HIGH-RESOLUTION UV TECHNOLOGY High-intensity line-source lamps provide a resolution better than 0.02nm, enabling excellent linearity over a wide dynamic range and leading to highly accurate measurements.
