Product Description
0.45mm Type S Precision Metal Thermocouple Wire
High accuracy temperature measurement solution for applications up to 1300℃
Product Overview
S-type noble metal thermocouple wire (0.45mm diameter) from Huona New Material is a high-precision temperature-sensing element composed of Pt10Rh (positive electrode, 10% rhodium-90% platinum alloy) and 99.99% pure platinum (negative electrode). Manufactured via vacuum smelting, multi-pass precision drawing, and high-temperature annealing, this wire delivers exceptional measurement accuracy, long-term stability, and high-temperature performance.
Standard Designations & Material Foundation
