2 channel premium thermopile detector for IR gas analysis of nitric oxide (NO) with a CWL of 5300 ± 30 nm and a HBW of 200 ± 20 nm. Application areas of such measurement applications are mainly in the industrial gas measurement of process gases or exhaust gases. The particularly high detectivity of up to 6.27*10^8 cmHz^1/2/W, as well as the very high sensitivity of up to 171 V/W, provide a signal quality comparable to pyroelectric detectors. The integrated thermistor for reference temperature determination, an interference absorber and an additional reference channel (CWL: 3910 ± 28, HBW: 70 ± 10 nm) optimize the measurement results of the dual IR detector. Storage and operation can be performed between -20 and 85 °C. Two sensor chips with 200 bismuth antimony/antimony thermopiles each form the core for the 2 channel thermopile MTS2SENS200 nitrogen monoxide. Due to its high-end materials, the thermopile is particularly durable and delivers precise measurement results.
