The Thermocouple bare wire product series provides a variety of models and specifications, including K-type, J-type, T-type and E-type. Each model features a different combination of metals to accommodate different temperature ranges and environmental conditions.
These Thermocouple bare wires have high-precision temperature measurement capabilities and are typically able to achieve low temperature deviations. They have fast response speed and can accurately capture temperature changes, providing reliable data for real-time temperature monitoring and control.
Thermocouple bare wire is also flexible and customizable. They are usually in the form of exposed wires that can be easily bent, cut and installed where the temperature needs to be measured. In addition, depending on the specific needs, options such as different lengths, diameters and connectors are available to meet the requirements of specific applications.
