In the ceramic industry, controlling moisture content in powders and bulk solids can impact the purchase price, shipping costs, material handling, and, perhaps most importantly, the quality of the final product. When processing dry bulk solids such as ceramics, chemicals, pigments and minerals, the amount of moisture in the product can have a wide range of effects. A product’s quality, as well as transactions based on weight, can be adversely affected by improper moisture contents. In addition, the satisfaction of legal requirements that are present in many industries is a determining factor influencing a company to measure moisture content.
However, conducting frequent moisture content tests throughout the process or in the field has traditionally been difficult. In many cases, the primary barrier has been the expertise and time required to conduct such tests. Sophisticated moisture measurement devices often must be operated by trained personnel who can properly calibrate the equipment. Many also require meticulous sample preparation and disposal.
