摘要： A moisture indicator for a refrigeration system. The moisture indicator includes a body for retaining refrigerant. The body includes an inlet, an outlet and an opening. A display member covers the opening of the body. An inner side of the display member contacts with the refrigerant. A lens assembly displays the color of the display member to the naked eye. The lens assembly is arranged on a receiving groove formed at the outside of the display member. The lens assembly is sealed within the receiving groove. The moisture indicator allows a user accurately to identify the color of the display member without disturbing the flow of the refrigerant. It also allows the user accurately to determine when to replace a filter drier and when to supplement the refrigerant.
