The ErgoFET Push-Pull Force Gauge is a digital force gauge designed for displaying peak force and time duration with its easy to read LCD screen. It features accuracy within 1% of reading, expanded sensitivity with its low and high threshold settings and selectable units of measure: pounds (lbs.), Newtons (N), or kilogram-force (kgf). The threshold settings start with the low threshold at 0.8 lbs. and measures at 0.1 lb. increments up to its 300 lb. high threshold capacity. This force gauge is wireless, eliminating the annoyance of cables, cords, and wires. The Wireless ErgoFET Push-Pull Force Gauge uses a rechargeable lithium ion battery with a self-activating "sleep" mode after 3 minutes of non-use to extend battery life. This cost-effective and ergonomically handheld design makes testing easier and more closely simulates actual job tasks for one hand test applications. Use as a stand-alone or with clinical software package (included) or data collection software package (included). Clinic Software Package is an easy-to-use platform providing muscle testing and spinal range of motion protocols. Patient tracking, analysis, and comparison statistics are collected and narrative and graphic reports can be generated. Data collection software package is designed for research and education applications. The program simultaneously captures raw test data while displaying a real-time graph of the data. The data is saved in comma-separated values (CSV) format and can be opened in most spreadsheet programs for further analysis.
