The MPS2SENS sulfur dioxide is matched by its filter windows to analyze sulfur dioxide (SO2) with a CWL of 7300 ± 50 nm and a HBW of 180 ± 20 nm (reference channel with CWL: 5060 ± 25 and HBW: 100 ± 15 nm). The detector stands out due to its high detectivity of up to 4.0*108 cmHz1/2/W and a high sensitivity of up to 200000 V/W.

The pyroelectric sensor features 2 chips with a thin film CPM membrane in the core. (CPM: Ceramic Pyroelectrical Material). Further important product properties for long-term use in demanding applications: wide spectral sensitivity 2 - 15 µm (optimized from 3 - 5 µm), high sensitivity with a modulation frequency of up to 100 Hz, low microphone effect due to the low membrane mass, very low temperature dependence, amplified signal in current mode. The MPS2SENS sulfur dioxide provides reliable readings in environments between -20 and 85 °C for NDIR gas measurement in aerospace, industry and environmental technology.

Our sales team will be happy to arrange scale prices and possible individual adaptations with you.
