What are the right tools to check the heating unit? What influencing factors need to be considered for temperature calibration?
This SOP describes in detail the testing procedure for calibrating and adjusting the heating unit of a moisture analyzer.
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?
Deviations of a moisture analyzer are mainly influenced by three elements:
Temperature deviations are more likely than weighing deviations and have a bigger impact on the moisture result. Therefore, the frequency of tests that focus on temperature deviations is higher than for tests that focus on the weighing accuracy.
The following tests are recommended for performance monitoring of a moisture analyzer:
Systematic moisture analyzer testing minimizes risks and reduces costs. With the right SOP's testing is a piece of cake.

Is there a way to test both the heating and weighing unit at the same time? How often does this test need to be done?
The SmartCal test is a rapid test which checks the moisture analyzer’s overall functionality. This SOP describes in detail the testing procedure for testing the moisture analyzer using SmartCal.
