High-Performance High-Temp QQ20-K Type K Solid Thermocouple Wire - 1000 Ft (White Jacket)
For precise and reliable temperature measurement in extreme environments, choose this High-Temp QQ20-K Type K Solid Thermocouple Wire. Supplied on a generous 1000-foot spool, this wire is specifically engineered for demanding industrial applications where accuracy and durability are paramount, such as furnaces, kilns, heat treating, and other high-temperature processes.
Key Features & Benefits:
Type K Thermocouple Calibration: Utilizes Chromel (+) and Alumel (-) alloys, offering a wide temperature measurement range from approximately -200°C to +1260°C (-328°F to +2300°F) (actual continuous and intermittent limits depend on insulation, but for high-temp QQ/fiberglass, expect continuous up to 950°F (480°C) or higher depending on the specific insulation grade, potentially to 1200°F (650°C) or even 1800°F (980°C) for specialized high-temp fiberglass/ceramic options). This makes it incredibly versatile for diverse high-temperature applications.
20 AWG Solid Conductors: Features robust 20 American Wire Gauge (AWG) solid conductors. Solid wire provides excellent mechanical strength and resistance to vibration, ensuring long-term stability and reliability in industrial settings.
High-Temperature "QQ" Insulation (Likely Fiberglass/Braided): The "QQ" designation typically refers to a specialized, high-temperature, non-abrasive braided insulation (often fiberglass or ceramic fiber) impregnated with a high-temperature resin. This construction provides:
Superior Thermal Resistance: Designed to withstand continuous high temperatures.
Good Dielectric Strength: Maintains electrical integrity even at elevated temperatures.
Flexibility (Relative to Temperature): Offers good flexibility for installation, particularly for a solid wire at high temperatures.
Chemical Resistance: Impregnated with resins for improved resistance to moisture and some chemicals.
1000 Ft Spool: Provides a substantial length for multiple thermocouple fabrications, long runs, or extensive projects, reducing the need for splices and optimizing material use.
Reliable Temperature Sensing: Type K thermocouples are known for their stable output, good linearity, and resistance to oxidation in high-temperature oxidizing atmospheres (below 1000°C).
Versatile Applications: Ideal for a wide range of industrial temperature monitoring and control, including:
Industrial Furnaces and Ovens
Heat Treating Processes (e.g., annealing, tempering)
Glass and Ceramic Kilns
Foundries and Aluminum Processing
Boiler and Flue Gas Temperature Monitoring
Process Control and Automation
Color-Coded (White Overall Jacket): The overall white jacket provides clear identification, making installation and maintenance straightforward. (Standard ANSI color coding for Type K is Yellow for positive, Red for negative, often with a Brown or Yellow overall jacket, but "White" indicates a specific high-temp insulation or manufacturer's code.)
