The DHD-1 Digital Hand Dynamometer represents the latest electronic technology applied to the familiar design of hydraulic hand dynamometers. Utilizing electronic load cell transducers instead of hydraulic fluid mechanisms that are prone to leakage; the DHD-1 is extremely durable and designed to last for many years. Highly accurate grip strength measurement from 0-200 pounds (lbs.) or from 0-90 kilograms (kg) is digitally displayed on the LCD and up to 20 test results for each hand can be stored in memory. The built-in battery is long lasting and is easily recharged when connected to a PC using the USB cable included with the DHD-1. In addition, the DHD-1 includes Data Transfer Software (DTS) enabling test results to be downloaded to a PC.
