The K-type thermocouple is a cost-effective metal thermocouple widely used in industrial temperature measurement. It consists of a nickel-chromium (Ni:Cr=90:10) positive electrode and a nickel-silicon (Ni:Si=97:3) negative electrode, with a temperature measurement range of -200°C to 1300°C. Its core advantages include:

Performance Characteristics
?Good Linearity?: The thermoelectric EMF exhibits a linear relationship with temperature, facilitating signal processing. ?
?High Sensitivity?: Capable of rapidly responding to temperature changes, making it suitable for dynamic temperature measurement needs. ?
?Strong Oxidation Resistance?: Performs stably in oxidizing or inert atmospheres, but is not suitable for sulfur-containing, reducing atmospheres, or vacuum environments. ?
Low Cost?: Ideal for large-scale industrial applications. ?
Application Scenarios
Primarily used for measuring the temperature of liquids, gases, and solid surfaces in industries such as metallurgy, chemical processing, and food processing, including furnace temperature monitoring and reactor temperature control. ?
Precautions
Do not use directly in high-temperature sulfur, alternating reducing atmospheres, or vacuum environments. ?
