In field applications, K-type TC is used to detect high temperatures, and the temperature measurement of 200°C is generally used to detect RTD Pt100. Our commonly used K-type TC temperature range is usually above 0~500℃.

Therefore, taking CZ2177 as an example, its accuracy is 1℃. If K-type TC is used in the range of 0~200℃, the accuracy index will only be 0.5%.
