Description Grip strength is one of the most widely used clinical indicators of overall upper-extremity function, and a hydraulic hand-held dynamometer is the gold standard instrument for measuring it. This device uses a sealed hydraulic system to capture peak grip force with precision and repeatability, providing clinicians with objective data they can track over time to document progress, set rehabilitation goals, and determine functional capacity. The ergonomic handle adjusts to multiple grip span positions so it can accommodate different hand sizes, and the easy-to-read dual-scale dial displays results in both pounds and kilograms for convenient reporting in any measurement system. Key Features Sealed hydraulic system delivers accurate, repeatable grip strength measurements Dual-scale analog dial reads in both pounds and kilograms Adjustable handle accommodates five grip span positions for different hand sizes Peak-hold needle retains the highest reading for easy recording after the test Recognized standard for grip strength assessment in clinical and research settings Useful for rehabilitation progress tracking, functional capacity evaluations, and pre/post-surgical assessments Durable construction built for years of daily clinical use Specifications Type: Hydraulic hand-held dynamometer Measurement: Grip strength (isometric) Display: Dual-scale analog dial (lbs and kg) Handle Positions: 5 adjustable grip spans Indicator: Peak-hold needle Use: Clinical evaluation, rehabilitation, research
