Type J Thermocouple Bare Wire (JP/JN) – 1.0mm Diameter


Product Overview


This Type J thermocouple bare wire from Huona is a cost-effective, high-conductivity thermoelectric wire pair consisting of JP (Iron, positive leg) and JN (Constantan, negative leg), designed for low-to-medium temperature industrial applications. Manufactured via precision drawing and stress-relief annealing, it delivers consistent thermoelectric performance and excellent mechanical durability, making it ideal for use in general-purpose furnaces, ovens, and machinery where high oxidation resistance is not a primary requirement.



Core Specifications


  • Product Name: Type J Thermocouple Bare Wire (JP/JN Pair)
  • Alloy Composition:
    • JP (Positive Leg): Pure Iron (low-carbon, high-purity)
    • JN (Negative Leg): Constantan (Cu: ~55%, Ni: ~45%)

  • Diameter: 1.0mm (customizable: 0.3–3.0mm)
  • Tolerance: ±0.01mm
  • Form: Spool (standard length: 50m/leg; custom lengths available)
  • Thermoelectric Performance:
    • Accuracy Class: IEC Class 1 (±2.2°C or ±0.75% of reading, whichever is greater)
    • Thermoelectric Power: ~51.7 µV/°C at 100°C

  • Operating Temperature Range: -210°C ~ 750°C (continuous use)
  • Standards Compliance: IEC 60584-1, ASTM E230, GB/T 4989, RoHS 2.0
  • Manufacturer: Huona (Shanghai) New Material Co., Ltd.



Key Differentiating Advantages


1. High Thermoelectric Sensitivity


Type J wire offers a significantly higher Seebeck coefficient (~51.7 µV/°C at 100°C) compared to Type K or Type N, resulting in stronger output signals and improved measurement resolution, especially in low-temperature ranges. This makes it ideal for applications requiring precise readings below 750°C.

2. Excellent Electrical Conductivity


The iron-constantan pair exhibits higher electrical conductivity than nickel-based thermocouples, reducing signal loss in long-wire installations and enabling use in low-voltage measurement systems without significant noise interference.

3. Cost-Effective for General-Purpose Use


As an iron-based thermocouple, Type J offers a more economical alternative to nickel-based alloys, making it ideal for high-volume applications where the maximum operating temperature does not exceed 750°C.

4. Good Mechanical Strength & Flexibility


The iron positive leg and constantan negative leg provide balanced tensile strength and flexibility, making the wire suitable for both rigid probe construction and flexible installations in machinery and equipment.

5. Versatile Compatibility


Fully compatible with standard Type J thermocouple connectors, extension wires, and instrumentation, allowing easy integration into existing low-to-medium temperature measurement systems.
