DSE: Lesson 2. Determination Of Moisture Content

2.2 Indirect Methods. There are several methods developed to determine the moisture content rapidly. These include use of modern heating, measurement methods like infrared, microwaves, ultra sound, and spectroscopy. These methods are developed due to requirements of rapid, nondestructive and precise moisture content determination.
