Sheath: 316L stainless steel; diameter: 8mm (customizable: 3-12mm)
Connection head: Die-cast aluminum (IP65 protection, waterproof and dustproof)
Mounting thread: M20×1.5 (standard industrial thread)
Thermocouple wire: Nicrosil (NP) / Nisil (NN), diameter: 0.5mm (customizable: 0.3-1.0mm)
Chemical Composition: Positive (NP): Ni 84% / Cr 14% / Si 1.4%; Negative (NN): Ni 95% / Si 4.5% / Mg 0.1%
Compliant Standards: IEC 60584-2, ASTM E230, GB/T 4989, RoHS 2.0
Manufacturer: Huona New Material, certified to ISO 9001 and IATF 16949

Key Core Advantages
