Thermopile (single element type)



Thermopile detector

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 type of gas analysis by changing the band-pass filter(custom order product).

・High sensitivity in 3 to 5 μm spectral band
・TO-18 package
・High sensitivity
・High-speed response
・Built-in thermistor
・Low cost
