Key Core Advantages (Centered on Type N Stability & 316L Corrosion Resistance)

1. Superior Thermoelectric Stability

• Minimal Drift: Type N thermocouple exhibits significantly less thermoelectric drift compared to Type K at high temperatures (above 1000℃), ensuring long-term measurement accuracy.
• Wide Temperature Range: Continuous operation from -200℃ to 1300℃, making it suitable for both cryogenic and high-temperature industrial applications.

2. High Precision & Accuracy

• Class 1 Accuracy: Thermoelectric potential error ≤±1.1℃ (0–400℃) / ±0.4% t (400–1300℃), meeting the precision requirements for critical industrial process control.
• Fast Thermal Response: Compact sheath design provides a thermal response time (τ₅₀) ≤2s in air at 800℃, ideal for dynamic temperature monitoring.

3. Rugged Construction & Environmental Resistance

• 316L Stainless Steel Sheath: Provides excellent resistance to corrosion, pitting, and crevice attack, making it ideal for marine, petrochemical, and acidic environments.
• IP65 Connection Head: Die-cast aluminum head with IP65 protection, preventing ingress of dust and water, suitable for outdoor and wet industrial settings.

4. Secure Mounting & Easy Installation

• Standard M20×1.5 Thread: Enables secure, stable installation in process pipelines, equipment casings, and furnace walls, with adjustable insertion depth.
• Universal Compatibility: Compatible with most industrial temperature controllers, data loggers, and PLC systems.

5. Versatile Processability

• Flexible Termination: Connection head accommodates standard terminal blocks for easy wiring and maintenance.
• Customizable Options: Supports various sheath lengths, diameters, and mounting configurations to meet specific application needs.
