MONITOR LABS ATeledyneTschnologies Company S02/NO In Situ Multi-Gas Analyzer

The SM8200 combines state-of-the-art chemometric spectroscopic analysis software and second-derivative (d2) ultra violet (UV) technology with the proven features of the SM81XX series of analyzers to provide a rugged in situ analyzer. The SM8200 provides a unique innovative approach to monitoring SO2 and NO in utility and industrial process emission monitoring applications. This unique technology allows the SM8200 to measure the absorption of UV energy by SO2 and NO molecules, with no interference from H2O, CO, O2 or CO2 as is common with other analytical techniques. Unlike extractive...

CALIBRATION VERIFICATION Unequaled measurement accuracy is made possible through in situ dynamic gas calibrations for both zero and span. Zero gas can either be supplied via instrument air or a separate bottled gas. Selectable measurement cavities/ ranges and probe lengths that suited to a variety of combustion monitoring applications, including hot and dirty gases. Additionally, a variety of analog and digital inputs and outputs are available through the Analyzer Electronics Box a part of the CEMS data records. Major assemblies are easily handled mounts on a single port, with data...

TOP VIEW (HORIZONTAL FLOW) The transceiver contains the optical system which provides the spectral information that allows the second derivative based measurement values to be computed, with typical one-minute updates of SO2 and NO measurements. The measurement technique is also inherently compensated for changes in the light level which may occur as a result of lamp aging, gradual buildup of optical contamination on the exposed, but protected, retroreflector and window, and shifts in alignment due to temperature and mechanical stress. The optical system is temperature stabilized to...

The gas calibration technique can be activated either automatically at predetermined intervals, manually from the ERP or LUI, or via digital command. When the instrument enters the automatic gas calibration cycle, zero gas is first flowed into the measurement cavity to establish a true zero concentration baseline. Then, a high level calibration gas of known concentration is injected into the measurement cavity where it is measured at the same temperature and pressure as the stack gas. Purge and averaging times are menu selectable, and calibration values are output from the Enhanced Remote...
