Product Features
The InBody InGrip is equipped with advanced features for accurate and reliable grip strength measurement:
- High-Precision Load Cell Sensor: Unlike traditional spring-based dynamometers, the InGrip utilizes a load cell sensor for superior accuracy and reproducibility, minimizing hysteresis issues. This ensures consistent and reliable measurements over time.
- Wide Measurement Range: Capable of measuring grip strength from 1 kg to 100 kg, displayed in 0.1 kg increments.
- Clear VA LCD Display: A 3-inch VA LCD with backlight provides clear and easy-to-read measurement results.
- Handle Guide for Reproducibility: Features a unique handle guide that helps users consistently position their hand, reducing variability in measurements caused by inconsistent grip.
- Bluetooth Connectivity: Allows wireless communication with other programs and can link with professional InBody devices (e.g., InBody970, 770, 580, 570, 470, 380, 380N, 270, BWA) to display grip strength results alongside other body composition data.
