Enhanced industrial durability

Triple composite protective structure: The outer layer of 304H heat-resistant steel protective tube can withstand instantaneous high-temperature impact up to 1300°C, the middle layer of alumina ceramic fiber layer prevents furnace gas corrosion, and the inner layer of reference gas self-purification device can filter particles larger than 20μm, extending the probe's average service life under continuous carburization conditions to 18-24 months.
