EC9841AS NITROGEN OXIDES ANALYSER The EC9841AS Nitrogen Oxides Analyser uses microprocessor control and chemiluminescence detection to measure high concentration nitric oxide (NO), total oxides of nitrogen (NOX), and nitrogen dioxide (NO2). The EC9841AS analyser delivers excellent sensitivity and reliability by using a single measurement channel and gas sample accumulator to provide precise measurement of NO and NOX. Advanced signal processing provides continuous zero measurement and NOX, NO, and NO2 concentrations are corrected for fluctuations in gas temperature/pressure and NO2 converter efficiency. Data can be displayed either in parts per million (ppm) or milligrams per cubic meter (mg/m3). FEATURES • High concentration NO/NOX measurement using chemiluminescence detection. The EC 9841AS has been specifically designed for applications with NO ranges of 0 - 1000 ppm or 0 - 300 ppm (option). • Inbuilt LCD presents real time data, converter efficiency, instrument status and historical information in a digital or graphical format. User selectable screens provide access to all instrument setup and diagnostics menus. • Stored data can be retrieved via RS232, USB interface or the optional Ethernet connection and uploaded to a TCP/IP network. • Ethernet option facilitates data download from an analyser connected to the internet via a standard web interface. This feature also supports remote access to instrument parameters and the status output screen. • Auto zero pre-reactor control provides continuous zero function. • Inbuilt data logger uses flash ROM with storage capacity up to 135 days of 5 minute data.
