Frequently Asked Questions

These thermocouples are crafted from premium platinum and rhodium alloys. This specialized metallurgy provides the exceptional chemical stability and oxidation resistance required for high-temperature measurements that would destroy standard base-metal sensors.

The primary noble metal types are R, S, and B. Type R and S utilize different percentages of Platinum-Rhodium for very high precision, while Type B is designed for even higher temperature ranges, often up to 1700°C or more in industrial furnaces.

In these sectors, measurement integrity is non-negotiable. Noble metal sensors offer superior accuracy and a significantly lower drift rate over time compared to other thermocouples, ensuring that critical data remains reliable throughout long-duration experiments or flights.

The dual-tube configuration provides an extra layer of defense against mechanical stress and chemical contamination. This is particularly important in extremely aggressive furnace environments where a single sheath might be compromised, leading to premature sensor failure.

Yes, HK Calibrations offers the TC-113 Replacement Thermocouple Element for Types R, S, B, and C. This allows facility managers to maintain their existing protective housings while ensuring the internal sensing wire remains fresh and accurate, reducing overall maintenance costs.

The TC-114 is designed for the most extreme high-temperature applications. The platinum sheath provides the highest level of protection against contamination and oxidation, making it the gold standard for precision temperature monitoring in glass manufacturing and specialty metal processing.
