Standard gas filter sets for reference, CO, hydrocarbon, CO₂
The quad thermopile sensor consists of four single thermopile chips mounted in a TO 5
h.ousing with a thermistor as temperature reference. The window size is 1.5 x 1.5 mm²
each. Due to the overall small sensor size the construction of a very compact equipment
becomes possible.
Applications in automotive exhaust gas control, multiple gas detection for the safety product
market or air quality monitoring
