All Gasmet FTIR analyzers are supplied with Calcmet software. The software collects, stores and visualizes the FTIR spectra of the sample gas and analyzes the concentrations of gas components.

The Calcmet software provides outstanding analytical performance. The software analyzes the sample spectrum using a sophisticated algorithm. Calcmet is capable of simultaneous detection, identification, and quantification of up to 50 different gas components from a single sample. Cross-interference effects are compensated for and analysis accuracy is maintained even when analyzing complex gas mixtures where gases have overlapping absorption spectra. Calcmet software comes with an easy to use user interface allowing simultaneous viewing of concentration results, sample and reference spectra, and time trends for the analyzed gases. The results are available within seconds.

Sample spectra can be easily re-analyzed, since the sample spectra are stored as separate files on an external computer. Calcmet software also allows the identification of previously unknown components – a feature that has often shown its value in process control.

Calcmet supports various input and output formats, which enable integration of the Gasmet gas analyzers to continuous emissions monitoring systems (CEMS) and to a variety of data acquisition systems. Typical inputs include analog signals and digital inputs from e.g. stack temperature and pressure sensors, flow measurement devices and particulate matter analyzers. Typical outputs include relay outputs used to control sampling systems, outputs of measured concentrations, and serial Modbus output consolidating both measured concentrations and binary alarm/status signals. Conversion of Modbus to other FieldBus formats is also supported.

The software provides easy and efficient processing of the results. Since water content of the sample gas is continuously measured with the Gasmet, the results can be reported on either a “wet” or “dry” basis. The results can also be compensated for the correct oxygen levels.

Calcmet comes in two versions, Calcmet Standard and Calcmet Pro.
