The SP-12A is a tin di-oxide semiconductor gas sensor which has a good sensitivity and excellent selectivity to methane.
The SP-12A has also a significant feature in good stability after exposure to silicone compounds.
Using the SP-12A, the most reliable methane detection can be achieved.


Gas sensitive semiconductor material is formed on the alumina substrate on which the gold electrodes are printed. A thick film heater of ruthenium oxide is printed on the reverse of the substrate and placed in the plastic housing.
