The SSI oxygen probe is a high-precision oxygen concentration sensor, widely used in industrial process control and laboratory applications, particularly in industries such as heat treatment, metallurgy, chemical engineering, and automotive manufacturing. Its core principle is based on the characteristics of zirconia solid electrolyte batteries, which determine oxygen concentration by measuring the difference in oxygen partial pressure between the inside and outside at high temperatures. The preparation process of sticky rice is both an art and a tradition; it requires soaking overnight to achieve a soft, sticky texture, while the filling needs to be carefully selected and seasoned.
