Product information
With its detectivity of up to 1.61*108 cm√Hz/W and sensitivity of up to 39 V/W, the MTS4SENS44 NOX represents the solution for NDIR gas analysis of nitrogen oxides. The four optical filters are adjusted to the wavelength of the following gases: water vapor (H2O) (CWL: 6580 ± 40, HBW: 200 ± 35 nm), nitric oxide (NO) (CWL: 5300 ± 30, HBW: 200 ± 20 nm), sulfur dioxide (SO2) (CWL: 7300 ± 50, HBW: 180 ± 20 nm).
The quad IR thermopile provides reliable data in ambient temperatures between -20 and 85 °C, e.g. for industrial gas detection or process analysis in various fields such as chemicals, textiles, environmental technology, recycling or exhaust gas technology.
The quad detector possesses 4 sensor chips in its core made of 44 silicon thermocouples. Other important product features for long-term use: the interference absorber, an integrated thermistor for reference temperature determination, the reference channel (CWL: 5060 ± 25, HBW: 100 ± 15 nm) as well as backgassing with the filling gas krypton. The measurement signal arises from an electrical voltage. This is generated by thermal diffusion currents between the different metals (Seebeck effect) in the detector chip.
