Moisture analyzers, also called moisture balances, are instruments that automatically determine the amount of moisture present in a sample. Moisture balances are used in many industries, such as pharmaceuticals, food, and plastics, for quality control. Some moisture analyzers use a loss on drying method to determine the percentage of moisture in the sample. The sample is placed on a weighing mechanism and then a heat source is turned on.
Moisture content is analyzed by determining the difference between the weight of the sample before and after evaporation. Other moisture balances may use absorption spectroscopy, where the gas from the evaporated moisture creates a spectrum that can be analyzed for content.
Considerations for purchasing a moisture analyzer or balance?
Moisture analyzers can have features thatvary between models. Among these features are speed, sample capacity, heat source, ease of user interface, customizable programs, scale resolution, and the percentage of moisture that can be detected.
