Set of five (5)
The HMS J21 F3.91 Miniature Thermopile Sensor is ideal for gas sensing, with a 3.91 um filter for using as a reference channel.
The HMS Series of CMOS compatible thermopile sensor chips in TO46 (or TO18) and even smaller transistor housings, features good sensitivity, small temperature coefficient of sensitivity as well as high reproducibility and reliability. The smaller package sizes benefit applications in which sensor mounting is a critical parameter.
