Test leads, thermocouples, and temperature probes are essential tools in the field of electronic test and measurement. Primarily, these products are designed for temperature detection and measurement. Test leads are the connecting cables that enable thermocouples and temperature probes to relay temperature data to measuring instruments, such as digital multimeters or specialized temperature meters. Thermocouples are sensors that measure temperature based on the voltage created by the temperature difference between two different conductors. Temperature probes, often encased in metal or plastic, are engineered to detect temperature levels and typically provide faster and more localized readings than thermocouples.
The main uses of these products span a variety of fields including industrial manufacturing, automotive diagnostics, HVAC (heating, ventilation, and air conditioning) system testing, and laboratory research. Key characteristics include high accuracy, durability under extreme conditions, and versatility to suit various measurement environments. Manufacturers such as Fluke, Omega Engineering, and Thermosense offer an array of these test and measurement components.
