Ultra-High Temperature Mastery: The product Excellence
The product stands as a premium choice for extreme temperature measurement, crafted with tungsten and rhenium as core materials to deliver exceptional heat resistance and thermal stability. Unlike ordinary thermocouples, the product operates via a thermoelectric circuit formed by two tungsten-rhenium alloy wires with distinct compositions, generating electromotive force to accurately capture temperatures in high to ultra-high temperature environments. Whether for industrial furnaces, aerospace testing, or laboratory research, the product excels in scenarios where reliability under extreme heat is non-negotiable, making it an indispensable tool for demanding temperature monitoring tasks.

Premium Materials & Trusted Grades of product
Every product is built with high-quality materials to ensure performance under extreme heat. Its core electrode is tungsten-rhenium alloy, combining tungsten's high melting point with rhenium's ductility and oxidation resistance. Insulation relies on high-temperature ceramic tubes (alumina, beryllium oxide) or magnesium oxide (for vacuum/inert environments), while protective tubes vary from corundum ceramic (regular high temperatures) to molybdenum/tantalum/tungsten tubes (harsh ultra-high temperature conditions).
Following GB/T 16839.1, the product offers two accuracy grades: Class Ⅰ (allowable error ±1℃ or ±0.5%|t| for 0~1800℃) for precision monitoring, and Class Ⅱ (±3℃ or ±1%|t|) for general industrial use. Protection grades reach IP54~IP65 for assembled/armored types, resisting dust and splashing water. Ideal for metallurgy, building materials, chemical engineering, aerospace, and laboratory settings, this thermocouple delivers consistent reliability where ordinary sensors fail.
