EC9832 CARBON MONOXIDE ANALYSER The EC9832 Carbon Monoxide analyser combines the benefits of microprocessor control with the NDIR gas filter correlation photometry to measure CO with minimal interference from CO2 and/or H2O. • Software controls all instrument functions including the performance of diagnostics, system status, output signal linearity and the calculation of CO concentration. The CO concentration is automatically corrected for gas temperature and/or pressure changes and can be displayed in units of parts per million (ppm) or milligrams per cubic metre (mg/m3). • Operator input functions are limited to routine maintenance and periodic calibration of the unit. The EC9832 has been designed for CEMS applications including the monitoring of CO emissions from industrial processes including steel mills, thermal power plants, gas turbines, municipal waste incinerators and boilers. • The infrared source and advanced materials in the gas filter wheel facilitates trouble free, long life operation with minimal maintenance requirements. • The EC9832 minimises interference from H2O and/ or CO2, fluctuations in the infrared source output or vibration and/or accumulation of dust on the optics. • 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 enables the user to download data from an analyser connected to the internet via a standard web interface. It also supports remote access to instrument parameters and display screen using a web browser. • nbuilt data logger uses Flash ROM to store up to I 175 days of 5 minute averaged data.
