Product Description
Huona Class 1 Type S Thermocouple Wire 0.275mm Customized
Product Overview
The S-type thermocouple wire (0.275mm diameter) from Huona New Material is a high-precision noble metal temperature-sensing element composed of Pt10Rh (positive electrode, 10% rhodium-90% platinum alloy) and pure platinum (negative electrode). This ultra-fine 0.275mm-diameter wire maintains stable thermoelectric potential performance across 0-1300℃ (continuous) / 0-1600℃ (short-term), offering ultra-high measurement accuracy, excellent high-temperature oxidation resistance, and good mechanical ductility.
Standard Designations & Core Material Foundation
- Thermocouple Type: S-type (Pt10Rh/Pt; single platinum-rhodium thermocouple, compliant with IEC 60584-2 Class 1)
- Key Specification: 0.275mm diameter (custom ultra-fine specification; tolerance: ±0.002mm)
- Chemical Composition: Positive electrode (SP): Pt90Rh10; Negative electrode (SN): 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 Core Advantages
1. High-Precision Temperature Measurement
- Class 1 Accuracy: At 0-1300℃, the thermoelectric potential error is ≤±1.5℃ (0-600℃) and ≤±0.25% t (600-1300℃)
- Stable Thermoelectric Potential: After 1000 hours at 1200℃, thermoelectric potential drift is <3μV (equivalent to temperature error <0.4℃)
2. Ultra-Fine Specification Advantages
- Miniaturized Application Adaptability: 45% thinner than standard 0.5mm S-type wire
- Fast Thermal Response: Thermal response time (τ₅₀) ≤1.5s (in air at 800℃)
3. Excellent High-Temperature Performance
- Wide Temperature Range: Continuous 0-1300℃; short-term up to 1600℃
- Mechanical Ductility: Tensile strength 320-380 MPa, elongation ≥20%
