For both the Jamar Smart and Jamar Plus+ we’ve replaced the hydraulic system found in other dynamometers with a circuit board and electronic load sensors. This technological advancement gives you a more accurate tool to measure hand strength in clients with hand trauma and dysfunction. We also increased the durability of the dynamometer by eliminating all internal moving parts, and encasing the electronics in a sturdy aluminum body with a scratch-resistant UV coating.
The Jamar Smart is the first electronic hand dynamometer that works seamlessly and wirelessly with a mobile app. Download the free Jamar Smart app from the Apple App Store, and you’ll be able to control your Jamar Smart from your iPad tablet (iPad Air, iPad Mini or original iPad version 3 or later). The app is designed to expedite and enhance patient evaluations allowing results to be quickly repeated, edited, and saved.
