Catalog excerpts

EC9850A SULFUR DIOXIDE ANALYSER • Menu selectable data trending graphically displays up to 100 data points. The EC9850 Sulfur Dioxide Analyser combines microprocessor control with pulsed UV fluorescence detection to measure SO2 in the ranges of 0-50 ppb and 0-20 ppm with a detection limit of 0.5 ppb. • Auto zero routine periodically checks and corrects for background illumination, virtually eliminating zero drift. Improved performance, sensitivity, noise and zero drift specifications are obtained through the use of a highly efficient reaction cell and electronics package. • The micro processor facilitates total external remote control and provides up to 100 channels of instrument parameters. • Inbuilt data logger utilises Flash ROM to store up to 175 days of 5 minute data averages. • Stored data can be retrieved via RS232, USB interface or the optional Ethernet connection and STANDARDS uploaded to a TCP/IP network. • Ethernet option facilitates data download from an • Complies with U.S. EPA Automated Equivalent analyser connected to the internet via a standard Method EQSA-0193-092. web interface. This feature also supports remote • Complies with Australian standard: AS 3580.4.1 access to instrument parameters and status. FEATURES • Large Graphic LCD display provides continuous output of instrument status including gas concentration, real time zero/span calibration curves and sample flow and pressure graphs. • The use of the zinc lamp reference source reduces SO2 and water vapour interference to provide maximum sensitivity, long lamp lifetime and a lower Total Cost of Ownership (TCO). • Optional internal pump and internal 12VDC power supply enables the EC9850A to be operated from a battery or solar power source for remote or mobile applications.
