Purpose

Thermocouple protection tube for measuring temperature

Mainly used for protection of temperature measuring element,make temperature measuring element separate from outsid,minish or avoid being corrasio, oxidation or damage caused by outside substance during the course of use.

Insulated tube

Mainly used for the separation of different poles of temperature measuring element,to avoid the interfere of two poles or connecting short circuit,which make temperature correct.

Usage

Thermocouple protection tube for measuring temperature

When  When using,put temperature measuring element which have been well insulation protection into

Protection tube.Then adhere and sealthe hatch and head of thermocouple by high temperature pasty cement.When measuring temperature,insert the sealed end into zone of measuring temperature.

Avoid rapid cold and rapid hot when using,which can prevent the protection tube from damage.

Insulated tube

When using,insert the two poles of temperature measuring element in the same direction into different holes.After ready,can be protected by protection sheath.
