With its filter window, the MTS2SENS44 sulfur dioxide matches the analysis of sulfur dioxide (SO2) with a CWL of 7300 ± 50 nm and a HBW of 180 ± 20 nm. The detector offers a good price/performance ratio with a detectivity of up to 2.21*108 cmHz1/2/W and sensitivity of up to 54 V/W with the fill gas krypton.

The dual channel IR thermopile for NDIR gas analysis possesses 2 chips in the core, each with 44 silicon thermopairs. The mass absorber, an integrated thermistor for reference temperature determination as well as the reference channel (CWL: 5060 ± 25, HBW: 100 ± 15 nm) represent further important product features for long-term use in a wide variety of applications. The MTS2SENS44 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 graduated prices and possible individual adaptations with you. Technical information is clearly summarized in our data sheet.
