Type K J Thermocouple can directly ,measur and display the temperature of various media in the range of 0~1200℃ in different production process, and is widely used in metallurgy, chemical industry, textile, printing and dyeing, papermaking, rubber, plastic, ceramics, granary, home appliances, food and other industries.
Type K And Type J Thermocouples Each Have Their Own Advantages:
Type K J Thermocouples have the advantages of good linearity, large thermoelectric potential, high sensitivity, good stability and uniformity, low price, etc.
Type J thermocouples and type K thermocouples have their own characteristics and advantages in temperature measurement. Type J thermocouples are suitable for a wider temperature range and have higher measurement accuracy, while type K thermocouples are suitable for high temperature environments and have better anti-oxidation and corrosion resistance.
Therefore, when choosing a thermocouple for temperature measurement, we need to select the appropriate type according to the specific application scenario and requirements, and perform correct installation and calibration to ensure the accuracy of the measurement.
