Calcmet professional

Calcmet is used together with Gasmet gas analyzers to collect FTIR spectra of the sample gas and to analyze the concentrations of gas components. Calcmet provides an easy to use interface to the FTIR gas analyzer, stores and visualizes the sample spectra and performs the multicomponent analysis using Gasmet Technologies Oy’s patented modified classical least squares algorithm.

Calcmet also 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 0-10 V and 4-20 mA 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, 0-10 V and 4-20 mA 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.

Calcmet comes in two versions, Calcmet Standard and Calcmet Pro. The Pro version offers additional features including automatic identification of gases based on a Library Search routine.
