These sensors are conveniently sold as a set of five (5). Thus, qty. 1 = 5 sensors, qty. 2 = 10 sensors, etc.
The HMS J21 F3.37 Miniature Thermopile Sensor is ideal for HC gas sensing, with a 3.37 um filter.
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.
