Infrared Detectors Quad channel sensor for HC (hydrocarbon), CO (carbon monoxide) and CO2 (carbon dioxide), Filters: 3.375um/190nm, 3.91um/90nm, 4.26um/180nm, 4.64um/180nm. Pyreos Thin Film Quad Channel Pyroelectric Sensors are highly stable four element sensors that provide high sensitivity with fast frequency operation in a TO39 package. These current mode sensors offer up to 100Hz data monitoring and feature internal CMOS trans-impedance amplifiers with 10GΩ feedback resistors. These feedback resistors output voltage signals are centered around half the supply rail. The thin film quad channel pyroelectric sensors are able to detect a variety of gases when used with different combinations of filters. These sensors with additional two channels will increase the accuracy of gas detection. https://elecena.pl/product/17083212/infrared-detector-for-hc-co-co2 2020-07-25 https://elecena.pl/product/17083212/infrared-detector-for-hc-co-co2 2020-08-04 https://elecena.pl/product/17083212/infrared-detector-for-hc-co-co2 2022-01-18 https://elecena.pl/product/17083212/infrared-detector-for-hc-co-co2 2022-01-19
