Key Core Advantages (Centered on Ceramic Sheath & High Temperature)

1. Ultra-High Temperature Capability

• Continuous Operation: Up to 1600℃, short-term up to 1700℃, suitable for extreme high-temperature industrial environments.
• Thermal Shock Resistance: 95% alumina ceramic sheath withstands rapid temperature changes without cracking, ensuring stable performance in furnace cycling.

2. High Precision & Excellent Linearity

• Class 1 Accuracy: Thermoelectric potential error ≤±1.0℃ (0–1100℃) / ±0.1% t (1100–1600℃), meeting the highest precision requirements for temperature measurement and calibration.
• Good Linearity: Consistent thermoelectric characteristics across the entire temperature range, simplifying data processing and system calibration.

3. Superior Corrosion & Contamination Resistance

• Ceramic Sheath Advantage: 95% alumina ceramic is inert to most chemicals and prevents contamination of high-purity processes (e.g., semiconductor manufacturing, ceramic sintering).
• Noble Metal Advantage: Platinum-based thermocouple wire provides excellent oxidation resistance in oxidizing and inert atmospheres.

4. Rugged Connection Head & Easy Installation

• Die-Cast Aluminum Head: IP65 protection against dust and moisture, suitable for industrial environments.
• Standard Mounting: Threaded or flange mounting options (customizable) for secure installation in furnaces and equipment.

5. Stable Mechanical Properties

• Uniform Sheath Dimensions: Strict tolerance control ensures consistent sheath diameter and length across batches, reducing installation variability.
• High Surface Quality: Smooth ceramic surface minimizes heat transfer resistance and ensures reliable thermal response.
