thermopile sensors / duals

duals - hts e-series

the htse multichannel sensors comprise two independent sensor chips for a multichannel gas concentration measurement. typically one of the optical channels contain a gas specific filter window and the other channel, equipped with a filter with center wavelength where no gas absorption occurs, serves as reference. of course we can also provide multichannel sensors with customer filters (thickness should be close to 0.5 mm). the sensors are offered in to-39 housings.
