The MTS2SENS200 sulfur dioxide is tuned by its filter window for the analysis of sulfur dioxide (SO2) with a CWL of 7300 ± 50 nm and a HBW of 180 ± 20 nm. The signal strength of the detector is comparable to that of a pyro detector - high detectivity of up to 6.27*108 cmHz1/2/W and high sensitivity of up to 171 V/W with krypton as filling gas.

The dual-channel IR thermopile for NDIR gas analysis has 2 chips in the core, each with 200 BiSb/Sb thermopairs. The interference absorber, an integrated thermistor for reference temperature determination and the reference channel (CWL: 5060 ± 25, HBW: 100 ± 15 nm) are further important product features for long-term use in demanding applications. The MTS2SENS200 sulfur dioxide provides reliable measurement values in environments between -20 and 85 °C, e.g. for biotechnology or quality assurance.

Our sales team will be happy to discuss further scale prices and possible individual customizations with you.
