A thermocouple is a temperature-sensing device made from two dissimilar metal wires joined at one end, generating a voltage in response to temperature differences, commonly used in industrial, HVAC, and scientific applications.

• Measures a wide range of temperatures (type-dependent; e.g., −200°C to +1300°C)
• Fast response time and high sensitivity
• Available in various types (K, J, T, E, etc.) for different applications
• Durable construction with metal or ceramic sheathing
• Compatible with digital thermometers, controllers, and data loggers
• Compact and flexible for easy installation in tight spaces
• Commonly used in furnaces, engines, heaters, and refrigeration systems
