2026 Queling 500kg High‑Precision Isometric Strength Tester, Push/Pull Force Sensor, APP Intelligent Control, Supports Rate of Force Development (RFD) & Peak Force Detection — Package 2

Product Information

About this item

• Standard Mode: Tests maximum strength and explosive power (Peak Force, RFD, Impulse), generally with rapid force exertion lasting 3‑5 seconds. Endurance Mode: Evaluates muscle anti‑fatigue capacity (Force Decay, Mean Force, Fatigue Index), with configurable durations of 10s/30s/60s. Force Control Mode: Trains neuromuscular stability by maintaining target force ranges, generating CV value, stability score and force drift. Supports Constant / Ramp / Staircase tracking modes.
• Bluetooth connection, real-time force curve display. Automatically generates PDF/image reports and supports Excel export of raw data. Member management, left-right limb comparison, historical trend graph. Supports multi-language, data collection, and device management.
• Indicator Definition Peak Force Maximum force output in a single contraction, reflecting absolute muscle strength Relative Peak Force Peak force normalized by body weight/individual profile for fair cross-comparison RFD (Rate of Force Development) Speed of force increase per unit time, representing explosive power Impulse Integral of force over time, reflecting overall work efficiency Mean Force Average force output during the entire test period
• Time to Peak: Time from exertion start to peak force, reflecting neural response speed.Force Decay / Force Drift: Force decline or shift over time, reflecting endurance and control stability.CV (Coefficient of Variation): Degree of force fluctuation, reflecting neuromuscular control ability.Left‑Right Comparison: Bilateral limb force difference, for balance and injury risk assessment.
