Measuring tennis racket swingweight
Inertia X1 is a professional application for measuring the swingweight of tennis rackets.
The app is designed to work in conjunction with the Inertia X1 measuring instrument by Pagal Lab, which uses an oscillating support to precisely determine the moment of inertia of the racket around the swing axis.
KEY FEATURES
• Swingweight measurement (moment of inertia around the handle axis)
• Twistweight calculation (difference between swingweight and spinweight)
• Recoilweight and polarization index calculation
• Built-in digital level for correct instrument positioning
• Racket archive with measurement history
• Data export in JSON format
HOW IT WORKS
The racket is mounted on the Inertia X1 instrument and set into oscillation. The smartphone's gyroscopic sensor detects the oscillation period and the app automatically calculates all dynamic parameters. The procedure takes only a few seconds and delivers laboratory-grade accuracy.
SETUP
The app is configured via the QR code on the instrument, which automatically loads the calibration parameters specific to each unit.
