The four-channel pyrodetector is optimized for gas analysis during anesthesia by four optical filters for the following gases: carbon dioxide (CO2) (CWL: 4265 ± 25, HBW: 120 ± 10 nm), nitrous oxide (N2O) (CWL: 4525 ± 20, HBW: 83 ± 6 nm), desflurane (CWL: 8224 ± 40, HBW: 240 ± 24 nm) and isoflurane (CWL: 8550 ± 40, HBW: 180 ± 18 nm). Medical, especially patient and anesthetic gas monitoring, represent typical application fields for the MPS4SENS anesthesia. The four-channel pyrodetector is particularly well suited for demanding applications in environments ranging from -20 to 85 °C.

The very high detectivity of up to 4.0*108 cmHz1/2/W as well as the very high sensitivity of up to 200000 V/W provide an extraordinary signal quality in the field of pyroelectric detectors. The quad detector is based on 4 sensor chips with a thin film CPM membrane. Thanks to the Ceramic Pyroelectrical Material (CPM) and the unique product design the detector convinces with a high read-out rate up to 100 Hz as well as with the short response time.
Additional important product features 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. Micro-Hybrid is the only one that can handle applications with such a compact design: We are the sole manufacturer to develop and produce quad pyrodetectors in the TO39 package.
