What Is the Benefit of Using Platinum in PRTs?

Platinum is the ideal material for PRTs due to its unique combination of chemical stability, electrical consistency, and physical durability. As a noble metal, platinum resists oxidation, corrosion, and contamination even at high temperatures, ensuring stable performance over many years. It has a highly predictable and linear resistance-temperature relationship, enabling accurate measurement across a wide range. Platinum maintains its physical and electrical properties without degradation, resulting in extremely low drift and long calibration intervals. High-purity platinum meets international standards such as ITS‑90, ensuring measurement traceability and uniformity. Platinum can withstand extreme temperatures, from cryogenic cold to high heat, without failure. Unlike other metals, platinum does not react with most chemicals, making it suitable for harsh industrial environments. The use of platinum distinguishes PRTs from lower-quality sensors, providing unmatched accuracy, stability, and reliability. For critical temperature measurement, platinum's inherent properties make PRTs the most trusted sensor technology available.
