Why is performance testing necessary for moisture analyzers?
A moisture analyzer consists of a heating device and an integrated balance. A fault in either component, or external influences such as the ambient temperature or drafts, can potentially cause errors in results. In order to verify that results are accurate, and conform to quality regulations if necessary, it is crucial to be sure that both components − the balance and the heating source − are functioning correctly.
What needs to be tested?
The accuracy of moisture analyzer measurements may be influenced by several factors. The three most
- Variability of the heating temperature
- Variability of the sample characteristics
- Error in the weighing results
