The HTS E21 F3.91/F3.375 Multi-channel Thermopile Sensor is ideal for gas sensing, with with 2 channels, a 3.375 um filter for CH detection and a 3.91 um reference channel.
The HTS Multichannel Sensors comprise two or four independent sensor chips for a multichannel gas concentration measurement. Typically one to three 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. On request we can also provide Multichannel Sensors with customer filters
