This 500g tubular spring scale can be used for both force and mass measurements. Each scale is calibrated in both Newtons and grams. The top is flat on one side so that the scale can be used with an inclined plane. The scales incorporate a unique zero adjustment. The main feature is the clear plastic tube, which allows students to see the action of the spring. Grades 4+
