IV. Frequently Asked Questions (FAQs)

How to choose different protection tube materials?

Answer: For oxidizing environments below 900℃, conventional 99% alumina tubes can be selected; For oxidizing environments above 900℃, 310S (2520) is selected; For temperatures above 1000℃, GH3039 or Inconel 600 is selected; For high-temperature scenarios above 1300℃, 99% alumina tubes must be used to meet the high-temperature resistance requirements.

What is the difference between installation in sealed and non-sealed environments?

Answer: For sealed environments, thread or flange connection methods must be used to ensure no gas leakage in the furnace and prevent the external environment from affecting temperature measurement; For non-sealed environments, direct installation is possible without additional sealing accessories, making the installation more convenient.

Is regular calibration required during the use of the product?

Answer: Yes. Annual calibration is recommended, especially under working conditions of long-term high-temperature use or frequent start-stop. Regular calibration can ensure measurement accuracy and avoid increased errors caused by electrode aging.

What are the advantages of this product compared with ordinary metal thermocouples (such as Type K)?

Answer: The core advantages lie in high-temperature performance and stability: Type K thermocouples have a maximum temperature resistance of about 1200℃, and are prone to oxidation and accuracy drift at high temperatures; Type WRP-100 platinum-rhodium thermocouples have a temperature resistance of up to 1500℃, and the precious metal material has strong oxidation resistance and stable thermoelectric potential, making it suitable for high-temperature scenarios with high requirements for measurement accuracy.
