The IR Thermopile can be used to measure methanol (CH4O / half structure formula: CH3OH) & ethanol (C2H5OH) at ambient temperatures between -20 and 85 °C. With its very high detectivity of up to 6.27*108 cmHz1/2/W and a sensitivity of up to 171 V/W, the 2-channel detector is the high-end solution for demanding applications in medical technology or industrial production and process applications. The optical filter window with a CWL of 9663 ± 80 nm and a HBW of 240 ± 40 nm is specifically designed for NDIR gas analysis of these typical alcohol compounds.

These signal values, which are comparable to pyrodetectors, are achieved by the interaction of chip design, an integrated thermistor for reference temperature determination, an interference absorber and backgassing with krypton. The precise measurement results are further secured by the second reference channel (CWL: 5060 ± 25, HBW: 100 ± 15 nm). The basis of the MTS2SENS200 alcohol is formed by two chips, each containing 200 bismuth-antimony/antimony thermocouples. The measurement signal is generated by an electrical voltage. This is generated by thermal diffusion currents between the different metals (Seebeck effect) in the detector chip.
