The HPS400600 (formerly OPT400600) is a core model in AMTI’s High Performance Series (HPS)—recognized globally as the most accurate force plates available. This platform is optimized using AMTI’s highest density calibration process, which includes up to 4000 applied loads across a dense surface grid, ensuring exceptional linearity and repeatability.
Designed for pediatric and adult gait studies, balance testing, and high-precision movement research, the HPS400600 delivers measurement accuracy down to ±0.1% and COP errors under 0.2 mm. The solid aluminum top plate and compact footprint (400 × 600 mm) make it suitable for standalone use or modular lab setups using AMTI’s Modular Rail System.
