Which measuring points or calibration points do you need?

When calibrating temperature probes, selecting the right measuring or calibration points is crucial for the accuracy and reliability of the measurement results.

The calibration points should be selected so that they cover and represent the typical application range of the temperature probe. In general, three calibration points are recommended:

Lowest point of the operating range: this point is at the lower end of the temperature range to be measured. It ensures that the probe provides accurate readings even at low temperatures.

Middle point of the operating range: This point is in the middle of the temperature range to be measured and is used to check the accuracy of the probe at normal operating temperatures.

Highest point of the operating range: This point is at the upper end of the temperature range to be measured and ensures that the probe provides accurate readings even at high temperatures.

The exact selection of calibration points should always be adapted to the specific requirements and operating conditions of the temperature probe. This ensures that the probe works reliably and accurately over the entire working range.
