2×0.35mm Type K Thermocouple Probe 1m Fiberglass Insulated Mini Plug Type
Product Description
Type K Thermocouple Probe (1m, 2×0.35mm, Fiberglass Insulation, Mini Plug)
Product Overview
Type K thermocouple probe from Tankii Alloy Material is a ready-to-use temperature-sensing assembly as shown, featuring a K-type (Chromel/Alumel) thermocouple junction, high-temperature fiberglass insulated lead wire, and a standard yellow mini thermocouple plug. Manufactured with precision welding and tight fiberglass braiding, it delivers stable thermoelectric performance across -40℃ to 700℃ (continuous) / 800℃ (short-term). Ideal for industrial temperature testing, HVAC, food processing, and laboratory use, it offers fast thermal response, excellent high-temperature insulation, and plug-and-play convenience.
Standard Designations & Core Material Foundation
- Thermocouple Type: Type K (Chromel/Alumel; compliant with IEC 60584-2 Class 1)
- Key Specification: 1m lead length; 2×0.35mm conductor diameter; fiberglass insulation; yellow mini Type K plug
- Chemical Composition: Positive (KP): Ni 89%/Cr 10%/Fe 1%; Negative (KN): Ni 95%/Al 2%/Mn 2%/Si 1%
- Insulation Material: High-purity alkali-free fiberglass (braided, temperature rating 700℃)
- Compliant Standards: IEC 60584-2, GB/T 4989-2013, ASTM E230, RoHS 2.0
- Manufacturer: Tankii Alloy Material, certified to ISO 9001 and IATF 16949
Key Core Advantages (Centered on Appearance & Specs)
1. Plug-and-Play Convenience
- Standard Mini Plug: Yellow Type K mini plug ensures universal compatibility with most handheld thermometers and data loggers, eliminating wiring errors and reducing setup time.
- Pre-Assembled & Ready-to-Use: Factory-welded junction and pre-terminated plug allow immediate deployment in field testing and industrial monitoring.
2. Superior High-Temperature Insulation Performance
- Fiberglass Insulation Reliability: Alkali-free fiberglass insulation resists 700℃ continuous high temperature, with no breakdown or carbonization after 1000 hours of operation at 650℃—far exceeding the 260℃ limit of PVC-insulated wires.
- Abrasion & Chemical Resistance: Tightly braided fiberglass sheath protects against mechanical wear and mild chemical exposure (e.g., furnace flue gas, oil mist), extending service life.
3. Fast Response & Measurement Stability
- Quick Thermal Response: 0.35mm diameter conductors provide a thermal response time (τ₅₀) ≤1.5s in air at 800℃, ideal for dynamic temperature monitoring.
- Class 1 Accuracy: Thermoelectric potential error ≤±1.5℃ (0-400℃) / ±0.4% t (400-700℃), ensuring reliable measurement data for industrial and laboratory applications.
