                      Tecera International

                      Protection ceramic tube

                      ■Application: 

                      Ceramic Protection Tube is mainly used for protecting the temperature measurement element from the outside world, in order to reduce or prevent the use of components in the process of being eroded by outside material, oxidation or collision damage. The Insulating Tube is an excellent production of Insulation material. Mainly for keeping components of the temperature measurement and the very different items off, avoiding contact with bipolar interference or short, accurating temperature measurement.
