How It Works

Three steps. Five minutes.

No laptop, no drivers, no software installation. Just a phone with a browser.

01
Mount

Stick the magnetic sensor on the spindle housing. Apply a strip of reflective tape to the spindle. Plug in USB-C power.

02
Connect

Open your phone's WiFi settings. Connect to "Grayvolt-XXXX". Your browser opens automatically with the measurement dashboard.

03
Measure

Start the spindle. Vibration data streams live. The Balancer edition tells you exactly where to add weight and how much. Done.
