Key Core Advantages (Centered on Type J & Sheath Design)

1. Superior Type J Thermoelectric Performance

• High EMF Output & Stability: Type J provides higher thermoelectric potential than Type K at lower temperatures (0–400℃), with error ≤±1.0℃ (0–200℃) / ±0.75% t (200–750℃), ideal for precision low-to-medium temperature measurement.
• Oxidation Resistance in Reducing Atmospheres: Performs reliably in reducing environments (e.g., furnace flue gas, inert gas) where Type K may suffer oxidation-induced drift.

2. Rugged Stainless Steel Sheath Protection

• Mechanical & Corrosion Resistance: 304 stainless steel sheath resists bending, abrasion, and mild chemical corrosion, extending service life by 3× compared to unprotected probes.
• High-Temperature Structural Integrity: Withstands continuous operation up to 750℃, maintaining shape and measurement accuracy in high-temperature industrial processes.

3. Flexible Silicone Lead & Plug-and-Play Convenience

• Silicone Insulation Performance: Operates stably at -60℃ to 200℃, with excellent flexibility (even at low temperatures) and IP65-level waterproof/oil resistance, suitable for wet and oily environments.
• Standard Mini Plug: Black Type J mini plug ensures universal compatibility with most handheld thermometers and data loggers, eliminating wiring errors and reducing setup time.
