Spindle Balancer
Single-plane spindle balancing on your phone — the influence-coefficient method gives you the exact correction weight and angle. Everything in the Analyzer, plus an integrated tachometer.
Everything in the Analyzer, plus integrated tachometer and automatic balancing algorithm. Tells you exactly how much weight to add and where.
- Everything in the Vibration Analyzer
- Integrated IR tachometer sensor
- Automatic influence coefficient balancing
- Sub-2.5 mm/s residual imbalance achievable
- Phase accuracy ±2–3°
- Includes tach sensor + 3.5mm cable
Three runs. Balanced.
The single-plane influence-coefficient method, automated end to end — no spreadsheets, no vector math by hand.
Bring the spindle to speed. The Balancer measures the 1× vibration amplitude and phase using the IR tach as reference.
Add a known trial weight and run again. The tool learns exactly how the rotor responds to mass.
The Balancer outputs the exact correction weight and angle. Add it, run once more to confirm sub-2.5 mm/s.
The balancing wizard, live.
This is the actual on-device interface — drag inside the polar to mark a trial weight and step through a real single-plane balance, right here in your browser.
Just your phone's
built-in browser.
Power the sensor. It spins up its own WiFi network. Connect — and your phone's captive portal pops open the measurement dashboard automatically. Same flow you already know from hotel WiFi.
See the difference.
Premium capability at a fraction of the cost. No laptop, no cables, no subscription fees.

Built for precision.
Industrial-grade components in a package smaller than a coin cell battery. Every spec chosen with purpose.
Every component, chosen with purpose.
The smallest wireless vibration sensor you can buy. Every part is here because it has to be — nothing extra, nothing missing.
Smaller than a
matchbox. Built like a brick.
SLA-printed Formlabs Tough 1500 resin shell. Neodymium magnet in the base for fast attachment to ferrous housings. VHB tape included for aluminum or plastic surfaces.
Balance anything that spins.
Single-plane correction for the rotating parts where imbalance wrecks finish, tools, and bearings.
Kill 1× vibration for better surface finish, longer tool life, and quieter bearings.
Balance wheels in place for cleaner grinds, less burn, and tighter tolerances.
Field-balance HVAC and process fans single-plane — no need to pull them from the duct.
Balance holders, arbors, and rotating fixtures to spec for high-RPM work.
