A novel power calibration method for microwave digestion system

摘要

For the importance of output power of microwave digestion system, the article proposes a new method for power calibration. It uses a wireless temperature probe instead of a platinum resistance thermometer to measure the temperature, and the measurement uncertainty is evaluated. Compared with the conventional method, an experiment shows that the calibration result is more accurate without changing the measurement uncertainty. This method can improve the calibration of output power, and guarantee the quality of all related works.
