These sleekly designed spring scales (dynamometers) are made from anodized aluminum construction to withstand years of use. 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 the desired maximum load. The steel hooks on both ends allow for easy connecting to a variety of objects. The metal screw on top makes for easy zero adjustment. The indicator is visible through a thin slot and aligns with easy-to-read numbers in both gram and Newton scales. Overall length is 9” and diameter is 5/8”. Available in a variety of weight capacities and color coded for easy reference.
