atmosFIR CEM is a complete emissions monitoring system incorporating the atmosFIR 19” FTIR analyser. As completely hot and wet emissions measurement, atmosFIR CEM is ideal for complete measurement of multiple gases from applications such as incineration and power. A standard gas suite of NO, NO2, N2O, SO2, NH3, HCl, CH4, O2, CO2 and H2O is provided, but with the powerful FTIR analyser, further gases can be added easily in software.

At the heart of system is the high-resolution, robust and proven FTIR spectrometer offering high signal throughput, low-noise and long lifetime of components. atmosFIR has been developed to incorporate the latest improvements and advantages in technology, The atmosFIR FTIR analyser contains an in-built sampling system and is designed for ppm-level emissions monitoring. The analyser can be used as a portable or bench-top unit as well as part of the installed CEM system.

For emissions applications, atmosFIR CEM contains complete management of the heated sampling system from within the system – heated lines, probes – as well as comprehensive span gas options, including 6 span valves that can be used to calibration the analyser directly or "to probe".

Protea’s PAS-Pro operating software not only collects and analyses the infrared spectra with the latest in analytical algorithms (with no limit on the number of gases that can be measured) but also manages the complete automation of the system. Modbus Serial, Modbus TCP/IP and OPC Server data exchange is provided as standard, and the monitoring results are reported both Raw and Corrected in real-time.
