The HIS-E222-F3.91/Fgas G4300 Dual Channel Integrated Thermopile Sensor is ideal for gas sensing, with with 2 channels, a selectable filter for CO2 detection and a 3.91 um reference channel. Typical infrared source to detector distance is 1 to 3 cm.
The HIS-E222 Multi-channel Sensor contains two thermopile sensors and signal amplification (gain is preset to 4300) all in a TO-39 package.
NOTE: For optimum performance you must select the CO2 filter that corresponds to the gas concentration you will be measuring. See the chart below. When ordering select the correct filter in the pull down menu above.
