Spring Scales, Clear Plastic, 1,000g/10N, 20g/0.2 N Graduations, Brown, Each

Details

This economically designed spring scale (or dynamometer) features a clear tube, allowing a clear view of its inner workings. The elongation of the spring corresponds to a specific force, noted on the scale. Different spring scales have different spring qualities to reflect their desired maximum loads. 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. 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.
