Product Description
K-Type Thermocouple Wire is used in a thermocouple from the sensing point to the cold junction compensation point (or reference point).Thermocouple wire or extension grade wire is recommended to be used to connect thermocouples to the sensing or control instrumentation. The conditions of measurement determine the type of thermocouple wire and insulation to be used. Temperature range, environment, insulation requirements, response, and service life should be considered.
K-Type Thermocouple Wire is used at temperatures up to 1260°C (2300°F). MICC thermocouple bare wire is supplied with bright or oxidized surface according to standard or special EMF requirements.Each individual lead is calibrated against platinum and the EMF values are shown on each coil or spool.
TYPE J (Iron vs Constantan) is used in vacuum, oxidizing, inert or reducing atmospheres. Iron element oxidizes rapidly at
temperatures exceeding 538'C, and therefore heavier gauge wire is recommended for longer life at these temperatures.
TYPE K (CHROMEL vs ALUMEL) is used in oxidizing, inert or dry reducing atmospheres. Exposure to vacuum limited to short time periods. Must be protected from sulfurous and marginally oxidizing atmospheres. Reliable and accurate at high temperatures.
TYPE T (Copper vs Constantan) is used or service in oxidizing, inert or reducing atmospheres or in vacuum. It is highly resistant to corrosion from atmospheric moisture and condensation and exhibits high stability at low temperatures. It is the only type with limits of error guaranteed for cryogenic temperatures.
TYPE E (CHROMEL vs Constantan) may be used in oxidizing, inert or dry reducing atmospheres, or for short periods of time under vacuum. Must be protected from sulfurous and marginally oxidizing atmospheres. Produces the highest EMF per degree o any standardized thermocouple.

Application Field
K-Type Thermocouple Wire operates efficiently in extreme temperature ranges. This makes them ideal for high-temperature applications where other thermocouple types would not perform accurately.
These thermocouples offer Class 1 accuracy, which can reach ±1.5°C or 0.25% of the reading. This precision is essential for scientific research and calibration applications where even minor temperature deviations could result in significant data errors.
The combination of platinum and rhodium ensures minimal drift in the EMF (electromotive force) output over time, providing stable and reliable measurements even in extreme conditions.
Both thermocouples feature superior oxidation resistance, which allows them to maintain their accuracy and functionality in high-oxygen environments, particularly at high temperatures.
These thermocouples are specially designed to operate in environments with minimal drift in their readings, ensuring that the precision of their measurements is maintained for long periods.
Due to their high-temperature resistance and exceptional accuracy, Thermocouple Alloy Wires are used in a variety of applications that demand precise temperature control and monitoring.
Calibration Laboratories: Thermocouple Alloy Wires are frequently used in calibration labs to ensure that temperature measurement instruments remain accurate. Their stable EMF outputs make them ideal for thermometer calibration and temperature standardization.
High-Temperature Testing: These thermocouples are used in materials research to study the properties of materials under extreme temperature conditions, helping scientists and engineers to test the behavior of materials in high-temperature environments.
Cryogenics: Although their primary use is for high-temperature measurement, S-Type thermocouples are also used in cryogenic research to measure temperatures accurately across a wide range.
Metallurgical and Steel Industries: Used in furnaces, kilns, and casting processes, Thermocouple Alloy Wires are essential for monitoring the temperature of molten metals, where precise temperature control is vital to maintaining the properties of the final product.
Aerospace and Aviation: Thermocouple Alloy Wires are used in jet engines and turbine testing, where they measure the extreme temperatures found in engine combustion chambers. Accurate temperature measurements are crucial for ensuring the performance and safety of aircraft.
Nuclear Industry: They are used in nuclear reactors to monitor and control the temperature in reactors, where maintaining precise thermal control is crucial for safety and efficiency.
Metrology Labs: Thermocouple Alloy Wires are used in high-precision temperature measurement, where they offer exceptional stability and accuracy for the most demanding measurements.
