The SP-53B-00 is a tin dioxide semiconductor gas sensor which has a good sensitivity to low concentration ranges of ammonia with improved response speed compared with conventional models.

Structure

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