The narrow-band filter of the MTS2SENS200 carbon dioxide with a CWL of 4265 ± 25 nm and an HBW of 120 ± 10 nm is optimized for the measurement of carbon dioxide (CO2) with reference channel (CWL: 3910 ± 28, HBW: 70 ± 10 nm). The detector is characterized by an integrated thermistor for reference temperature determination and an interference absorber ensures that the signal is converted as efficiently as possible from radiant energy to thermal energy - thermocouples then convert thermal to electrical energy.

The basis of the IR thermopile MTS2SENS200 carbon dioxide is 2 chips with 200 bismuth-antimony/antimony thermocouples each. Thanks to them and the filling with krypton, the detector convinces with a very high detectivity of up to 6.27*10^8 cmHz^1/2/W and sensitivity of up to 171 V/W. The signal quality is comparable to pyroelectric detectors and thus offers an additional alternative in the NDIR component range.

The detector can be used at ambient temperatures between -20 and 85 °C in numerous industrial, aerospace and medical applications: Exhaust gas measurement on vehicles, breath gas analysis or patient monitoring.

Customer-specific adaptations are possible at any time. Our sales team will be happy to advise you on this, as well as on graduated prices for an inquiry in larger quantities.
