The SP-19-01 is a tin di-oxide semiconductor gas sensor which has a high sensitivity and selectivity to hydrogen. Using this model, detection of hydrogen is possible from low concentration ranges.

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 is printed on the reverse of the substrate and placed in the plastic housing.

• Purpose：Safety
• Use：Industrial gas leak detector
• Target gas：Hydrogen
