Application
Ceramic thermocouple protection tubes are mainly used to protect the thermometric element, to isolate the thermometric element from the outside, and to reduce or prevent the element from being eroded, oxidized or damaged by external substances during use.
Feature
1. Good smooth and high strength.
2. Extreme hardness, good protection from abrasion and corrosion.
3. High-temperature resistance up to 1800℃
4. High dielectric properties.
5. Optimum air tightness
