EC9843 TOTAL REACTIVE NITROGEN OXIDES ANALYSER The EC9843 Total Reactive Nitrogen Oxides Analyser combines microprocessor control with chemiluminescence detection to measure NO and NOy in the ranges of 0-2000 ppb with a detection limit of 50 ppt. Improved sensitivity, noise, and zero drift specifications are obtained through the use of a superior low pressure reaction cell and an electronics suite to provide better all round performance. The EC9843 is used in conjunction with a NOy-1000 converter used for the conversion of NOy to NO for analysis. FEATURES • Large Graphic LCD provides continuous output of instrument status including, analyte concentrations, real time zero/span calibration curves, and sample flow and pressure graphs. • Menu selectable data trending graphically displays up to 100 data points. • Auto zero routine periodically checks and corrects for background illumination, virtually eliminating zero drift. • The micro processor facilitates total external remote control of the analyser and provides up to 100 channels of instrument operating parameters. • Stored data can be retrieved via RS232, USB interface or the optional Ethernet connection to a TCP/IP network via an RJ45 connector. • 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. • Inbuilt data logger utilises Flash ROM to store up to 132 days of five minute data averages.

SPECIFICATIONS Ranges: Auto-ranging for 0-50 ppb to 0-2000 ppb Data display: Large Graphic LCD display, with unit selection mg/ m3, µg/m3, ppm, ppb, ppt. Analogue out: 0 - full scale from 0 - 5 ppb to 0 - 2000 ppb with menu selectable offset of 0%, 5% or 10%. Autoranging between two user specified full-scale values. Noise: 25 ppt or 0.1% of reading with Kalman filter active. Lower detectable limit: 50 ppt or with Kalman filter active. Linearity: ± 1% of full scale (from best straight-line fit). Precision: 50 ppt or ±0.5 % of reading whichever is greater. Zero drift: 24 hours < 100 ppt; 30...
