What is a jelmeter?
A jelmeter is a graduated glass tube with an opening at each end. It is used to determine the amount of pectin in fruit juice. The rate of flow of the juice through this tube is used as a measure of the jellying power of the juice. Therefore, it is an index to the amount of sugar to be used.
