Tungsten Rhenium Thermocouple – The Ultimate Solution for Extreme Heat Measurement

In a high-temperature testing lab, an engineer struggled with repeated sensor failures. Every few days, thermocouples would degrade, readings would drift, and critical experiments would halt.

The issue wasn’t the system.

It was the material.

Switching to a Tungsten Rhenium Thermocouple changed everything — stable readings, longer life, and reliable data even above 2000°C.

That’s the difference the right alloy makes.

What is Tungsten Rhenium Thermocouple?

A Tungsten Rhenium Thermocouple is a high-performance temperature sensing wire made from tungsten alloyed with rhenium, typically in combinations such as W-3%Re / W-25%Re or W-5%Re / W-26%Re.

It is specifically engineered for ultra-high temperature environments where conventional temperature sensors fail.

DOMADIA™ supplies precision-engineered thermocouple wire for demanding applications where accuracy, stability, and durability are critical.
