Spring Scales, Clear Plastic, 3,000g/30N, 50g/0.5 N Graduations, Cream, Each

Details

This economically designed spring scale (or dynamometer) features a clear tube, providing an unobstructed view of its inner workings. The elongation of the spring corresponds to a specific force, which is denoted on the scale. Different spring scales have distinct spring qualities to reflect the desired maximum load. These color-coded spring scales feature both gram and Newton scales. The top loop and large S hook are made from durable steel, while the acrylic tube and spring are built to last. The top zero adjustment nut is easy to use. Overall length is approximately 9-1/2 inches, and diameter is 1 inch. Available in a variety of weight capacities, these scales are color-coded for easy reference. They are great for physics demonstrations and experiments.
