Ultra-High Temp Thermocouple Wire Type R 0.35mm

Ultra-High Temp Thermocouple Wire Type R 0.35mm
R-type noble metal thermocouple wire (0.35mm diameter) from Huona New Material is a high-precision temperature-sensing element composed of Pt13Rh (positive electrode, 13% rhodium-87% platinum alloy) and 99.99% pure platinum (negative electrode).
Standard Designations & Core Material Foundation
  • Thermocouple Type: R-type (Pt13Rh/Pt; noble metal thermocouple, compliant with IEC 60584-2 Class 1)
  • Key Specification: 0.35mm diameter (tolerance: ±0.002mm)
  • Chemical Composition: Positive (RP): Pt87Rh13; Negative (RN): 99.99% pure Pt
  • Compliant Standards: IEC 60584-2, GB/T 1672-1997, ASTM E230
  • Manufacturer: Huona New Material, certified to ISO 9001 and IATF 16949
Key Performance Advantages
Ultra-High Measurement Precision & Long-Term Stability
Class 1 top-tier accuracy with thermoelectric potential error ≤±1℃ (0-1100℃) and minimal drift of <2μV after 1000 hours at 1200℃.
Optimized 0.35mm Ultra-Fine Diameter Performance
Fast thermal response (τ₅₀ ≤1.8s) with tensile strength ≥340 MPa, ideal for narrow measurement spaces.
Excellent High-Temperature & Environmental Resistance
Operates continuously at 0-1300℃, withstands short-term exposure to 1600℃, with elongation ≥18% for complex sensor packaging.
