The Baseline Hydraulic Hand Dynamometer gives accurate grip strength readings without the subject being able to "feel" the handle move. The results are consistent with published Baseline and Jamar® studies. The internationally accepted design assures reliability, user convenience and measure­ment repeatability. The five position adjustable handle can accommodate any hand size. The maximum reading remains until the unit is reset. The strength reading can be viewed as pounds or kilograms. Each dynamometer comes in a molded carrying case.
