Thermopile detector
T11361-01
High sensitivity, for gas density measurement
The T11361-01 is a high-sensitivity thermopile detector ideal for measuring gas density. It uses a TO-18 package with a
window having high transmittance in the 3 to 5 μm spectral band. The T11361-01 can be used for various types of gas
analysis by changing the band-pass filter (custom order product).
