具有高固有频率的通用测功机，107 x 80 mm。测功机的设置可以精确测量非常小的力，并保证热效应的影响最小。

The Chatillon® DMG Series Dynamometer lets you objectively measure manual muscle strength and functional task requirements for almost any application. Offers full portability and ease of use for a fraction of the cost of expensive computer controlled systems. Available in 200 lbf and 500 lbf capacities, these rugged mechanical instruments accurately measure (+0.5% FS) instantaneous push or pull forces generated by the test subject. A calibrated dial shows instantaneous force. An easy-to-use peak force switch freezes the pointer at the maximum force for simple identification and analysis. Gauges come complete with handle assembly and carrying case. Use with optional Functional Capacity Kit (FCEK) or Muscle Strength Comparator Kit (MSCK). All DMG Series gauges come standard with a Certificate of Calibration with data verification to NIST.
