10 Channel Thermopile Detector

10 Channel Thermopile Detector

A ten-channel thin-film thermopile in a TO-8 package. Each active area is 3.16mm x 0.4mm and offers low noise voltage. Internal aperture minimizes channel-to-channel crosstalk while increasing sensitivity.

The perfect single package choice for analyzing multiple anesthetic gases in demanding environments such as hospital operating rooms. Potential applications in non-contact temperature and spectral discrimination of materials.

Ten-channel spectral differentiation for demanding applications.
