Spring Scales, Clear Plastic, 2,000g/20N, 40g/0.5 N Graduations, Red, Each

Details

This economically designed spring scale, also known as a dynamometer, features a clear tube that allows for an unobstructed view of its internal mechanisms. The elongation of the spring corresponds to a specific force, which is noted on the scale. Different spring scales have distinct spring qualities to accommodate various maximum loads. These color-coded spring scales feature both gram and Newton scales. The top loop and large S hook are constructed from durable steel, while the acrylic tube and sturdy spring are built to last. The top zero adjustment nut is easy to use. The overall length is approximately 9.5 inches, and the diameter is 1 inch. Available in a variety of weight capacities, these scales are color-coded for easy reference. They are ideal for physics demonstrations and experiments.
