PLEASE NOTE:
The moisture Analyzer is equipped with an overheating protection. At temperatures above 160°C, a time limit becomes active. The higher the temperature, the shorter the time until the instrument starts to lower the temperature. At 200°C the temperature will hold for 10 minutes then start to drop. It reaches 160°C in about 50 minutes.
