Designation: thermal conductivity principle and integrated selective infrared measurement
The FTC400 compact gas analyzer offers precise and reliable process monitoring based on the principle of thermal conductivity plus integrated selective infrared measurement of CO 2 , CH 4 , CO, H 2 O and other IR-active gases. In addition to (quasi-) binary gas mixtures of, inter alia, H 2 , He, Ne, Ar, N 2 , Kr, O 2 , CH 4 , CO 2 , NH 3 and SF 6 , complex gas mixtures can also be analyzed online by means of cross-sensitivity compensation.
H 2 in natural gas or biogas, for example, can be accurately determined. Of course, the concentrations of the IR-active gases can also be displayed and read out. The FTC400 is designed in enclosure IP65 and is specified for absolute sample gas pressures of up to 2 bar. A version for higher sample gas pressures is available on request. The FTC series operates without reference gases, even at the smallest measuring ranges of eg 0 vol.% - 0.5 vol.% Of H 2 in N 2 .
