The 2 channel premium pyrodetector is specially designed for the analysis of nitric oxide (NO). The optical filter with a CWL of 5300 ± 30 nm and a HBW of ± 20 nm as well as an additional reference channel (CWL: 3910 ± 28, HBW: 70 ± 10 nm) optimize the measurement results of the dual IR detector. Its main application lies in the measurement of process gases or exhaust gases in industrial production and process engineering. Storage and operation can take place between -20 and 85 °C. The particularly high detectivity of up to 4.0*10^8 cm√Hz/W as well as the very high sensitivity up to 200000 V/W provide an extraordinary signal quality in the sector of pyroelectric detectors. Two sensor chips with a thin film CPM membrane form the core of the dual detector MPS2SENS nitrogen monoxide. Thanks to the Ceramic Pyroelectrical Material (CPM) and the unique product design the detector features a high read-out rate up to 100 Hz as well as a short response time.

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*10^8 cm√Hz/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.

The high detectivity up to 4.0*10^8 cm√Hz/W as well as the high sensitivity up to 200000 V/W characterize the MPS2SENS flourane. The optical characteristics of the infrared filter windows perfectly suit the analysis of flouranes (CWL of 8620 ± 45 nm, HBW of 540 ± 45 nm, reference channel with CWL: 5060 ± 25, HBW: 100 ± 15 nm). The MPS2SENS sulfur dioxide provides reliable readings in environments between -20 and 85 °C for NDIR gas measurement in medical applications, e.g. anesthetic gas monitoring. The pyroelectric detector has 2 chips with a thin film CPM membrane in the core. (CPM: Ceramic Pyroelectrical Material). Other key 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.

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 pyrodetector is designed for applications in environments ranging from -20 to 85 °C. The very high detectivity of up to 4.0*10^8 cm√Hz/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.
