Spring Scales, Clear Plastic, 5,000g/50N, 100g/1 N Graduations, Yellow, Each

Details:

This economically designed spring scale, also known as a dynamometer, features a clear tube that provides an unobstructed view of its inner workings. The elongation of the spring corresponds to a specific force, which is noted on the scale. Different spring scales have different spring qualities to reflect their desired maximum load capacities. 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 sturdy spring are built to last. The top zero adjustment nut is easy to use. The overall length is approximately 9-1/2 inches, and the 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.
