Hamamatsu Photonics Europe GmbH Thermopile detectors T11722-11

High sensitivity thermopile detectors for CO2 concentration measurement The T11722 series is a dual type thermopile detector developed for high accuracy measurement of gas concentration. These consist of two highly sensitive Si thermopile detectors and two band-pass filters. The T11722-11 can simultaneously detect two wavelengths of 4.26 μm (for CO2) and 3.9 μm (for reference), and the T11722-12 can simultaneously detect two wavelengths of 3.3 μm (for CH4) and 3.9 μm (for reference). Features - 2 wavelengths detection - Metal package (TO-5) - High sensitivity
