K-Type Thermocouple Wire 2*0.8mm (800℃ Fiberglass) for High Heat
The Type K thermocouple cable (2*0.8mm) from Huona New Material is a specialized high-temperature temperature-sensing solution engineered for extreme industrial environments. It features two 0.8mm diameter core conductors (Chromel for positive, Alumel for negative)--the signature alloy pair of Type K thermocouples--with dual-layer protection: individual conductors insulated by 800℃-rated fiberglass, plus an overall 800℃ fiberglass sheath.
- Thermocouple Type: K (Chromel-Alumel)
- Conductor Specification: 2*0.8mm (two 0.8mm diameter thermocouple alloy conductors)
- Insulation/Sheath Standard: Fiberglass complies with IEC 60751 and ASTM D2307; rated for 800℃ continuous use
- Manufacturer: Huona New Material, certified to ISO 9001 and IECEx for hazardous/high-temperature applications
- Extreme Heat Resistance: 800℃ continuous operating temperature (short-term up to 900℃ for 1 hour)
- Dual-Layer Durability: Individual fiberglass insulation + overall fiberglass sheath doubles resistance to abrasion
- Uncompromised Signal Accuracy: 0.8mm Chromel-Alumel conductors minimize signal attenuation
- Enhanced Safety: Inherently flame-retardant (UL 94 V-0 rating), non-toxic, and low-smoke
