Product Information
Kinvent K-Grip is a digital wireless hand dynamometer for measuring grip strength, peak force, average
force, side-to-side differences, and fatigue.
Its magnetic changeable grip interface supports repeatable hand positioning for rehabilitation,
neurological assessment, and hand-function monitoring.
The 170 g device measures approximately 146.5×36×60.5 mm and captures up to 90 kg or 198 lb at 1000 Hz
with under approximately 0.2% accuracy.
Bluetooth 5.1 connects across up to approximately 40 m, while the rechargeable battery provides about 12
hours of operation and charges in roughly two hours.
Product Features
Digital grip measurement quantifies hand-force production with standardized positioning and responsive real-time feedback.
Peak and average force results support objective side-to-side comparison during rehabilitation and hand-function assessment.
Repeated contractions reveal fatigue-related performance while Kinvent App records help track changes across sessions.
