A Video vs. a Snap-Shot

Many standard reference tests rely on heating a sample at a temperature like 105C for a given period of time, from an hour to over night then cooling the sample, maybe in a desiccator and weighing. One source of error that people do not realize is that the sample might regain weight due to re-hydration. This means that the reference number is different from the moisture level the process will see.

The Computrac® MAX® family of analyzers has the ability to heat the sample to a given temperature and then monitor the change in weight as the sample cools. The benefit of using a Computrac® loss on heating analyzer is that you can get the moisture number at process temperature conditions. This means that the number you report is the number the process will see.
