Red porcelain ring

Affiliate classification
Temperature controllers with 95% alumina (AL2O3) are widely used in electrical appliances, electrothermal refrigeration ventilation equipment and many other industries. It not only has excellent reliability and practicability, but also has a high value-cost ratio because of its large-scale production.
