Temperature Calibration Set thermocouple calibration intervals from operating temperature, exposure, stability history, required accuracy, checks, and consequence of error. Contents How Often Should You Calibrate a Thermocouple? There Is No Universal Thermocouple Calibration Interval What Determines the Calibration Interval? Use Calibration History to Review the Interval When Should You Check a Thermocouple Early? How Is a Thermocouple Calibrated? What Should Your Calibration Procedure Define? What Is a Practical Calibration Interval? Simple Calibration Interval Review Sources Thermocouple Calibration How Often Should You Calibrate a Thermocouple? A thermocouple can continue to show a temperature reading even when its measurement performance has changed. Your calibration interval should therefore depend on measurement performance, operating conditions, required accuracy, and calibration history. The practical question is simple. How long can your thermocouple remain sui...
