United Scientific® SET OF 6 SPRING SCALES (ONE EACH OF ABOVE)

This economically designed spring scale (or dynamometer) features a clear tube, allowing a clear view to the 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 the desired maximum load.These color-coded spring scales feature both a gram and Newton scale. The top loop and the large S hook are both made from durable steel. The durable 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 L” and diameter is 1”. Available in a variety of weight capacities and color coded for easy reference. Great for physics demonstrations and experiments.
