Key Performance Advantages

Superior Type J Thermoelectric Performance

High EMF Output & Stability: Higher thermoelectric potential than Type K at lower temperatures (0-400℃)
Precision Accuracy: Error ≤±1.0℃ (0-200℃) / ±0.75% t (200-750℃)
Oxidation Resistance: Reliable performance in reducing environments where Type K may suffer drift

Rugged Stainless Steel Sheath Protection

Mechanical & Corrosion Resistance: 304 stainless steel resists bending, abrasion, and mild chemical corrosion
Extended Service Life: 3× longer lifespan compared to unprotected probes
High-Temperature Integrity: Withstands continuous operation up to 750℃

Flexible Silicone Lead & Plug-and-Play Convenience

Silicone Insulation: Operates at -60℃ to 200℃ with excellent flexibility and IP65 waterproof/oil resistance
Standard Mini Plug: Black Type J mini plug ensures universal compatibility with most handheld thermometers
Easy Setup: Eliminates wiring errors and reduces installation time
