For continuous measurement of hydrogen and noble gases, the thermal conductivity of the sample gas mixture is measured and used to calculate the concentration. Only binary gas mixtures can be measured directly. If more than two components are present, the concentration of all other constituents must be measured separately using other measuring methods. The CALOMAT 6 can carry out internal cross correction after transmission of the external measuring results. There is no need for an external computer.

The CALOMAT 6 is notable for its high measuring range dynamics (e.g. 0-1 % and 0-100% H2, can be parameterized) and a low T90 time.

The CALOMAT 6 is a high-end analyzer available in a 19" design or in a robust field unit for mounting in the open air. With its additional monitoring unit, the CALOMAT 6 with field unit is suitable to be installed in Ex zone 1 or 2. In general, its range of uses includes all areas from the measurement of gas purity measurement through to use in process monitoring and controls to insure product quality.

The analyzers can easily be added to an integrated automation system via RS 485, PROFIBUS DP and PROFIBUS PA interfaces, and can be parameterized and operated using the PDM tool. For fast and easy maintenance, the analyzers can also communicate with the Siprom GA software tool that is integrated into the Ethernet via TCP/IP.
