WRe thermocouple with molybdenum protection tube is a high-temperature temperature measurement solution specially designed for vacuum furnaces, sintering furnaces, and semiconductor processing equipment.

The assembly combines a WRe5/WRe26 tungsten rhenium thermocouple with a high purity molybdenum protection tube, providing excellent protection, temperature stability, and long service life in extreme environments.

The molybdenum protection tube protects the thermocouple wire from mechanical damage, thermal shock, and furnace contamination while maintaining accurate temperature measurement at temperatures up to 2300℃.

Zhishuo (Luoyang) Metal Products Co., Ltd. specializes in manufacturing tungsten rhenium thermocouples, molybdenum tubes, tungsten tubes, and customized high-temperature components, providing complete solutions for industrial furnace applications.
