küllastusmärke

Küllastusmärke, often translated as saturation marks or saturation indicators, are visual cues used to signal when a material has reached its maximum capacity for absorbing a particular substance. These marks are commonly found in applications where controlling moisture or other liquids is critical, such as in desiccants, packaging, or certain types of laboratory equipment.

The principle behind küllastusmärke is their ability to change color in response to the presence of moisture or other target molecules. This color change is usually a result of a chemical reaction or a physical property of the indicator material. For example, cobalt chloride, a common moisture indicator, is blue when dry but turns pink when it absorbs moisture. Other indicators might use different chemical compounds or a change in transparency to signal saturation.

The primary function of küllastusmärke is to provide a clear, unambiguous indication of a material's status. This helps users determine when a desiccant needs to be regenerated or replaced, or when a product has been exposed to excessive moisture, potentially compromising its integrity. The reliability and visibility of these marks are essential for ensuring product quality, preventing spoilage, and maintaining the effectiveness of moisture-sensitive items. They are a simple yet effective tool in a variety of industrial and consumer applications.
