Health professionals in physical education, corporate fitness, and sports medicine have made the Lafayette Hand Dynamometer their grip test standard because it is accurate, repeatable, and durable. Its custom twisted spring can easily withstand accidental dropping without affecting its accuracy. Also, during a grip test, the spring compresses providing the handle with a life-like, dynamic motion. This hand dynamometer features a dual pointer system to retain the maximum effort and 4 centimeters of infinite handle adjustment for the most comfortable fit. Testing range on dual scale is 0 to 100 kilo-grams/0 to 220 pounds. Unit comes complete with carrying case and norms for ages 5 through adult.
