New measurement program apps for this company’s AliSensor Level System enable users to quickly measure vertical-shaft plumbness to an angle accuracy of down to 0.001 deg. With an adapter, the AliSensor is mounted to the shaft vertically and measurements are taken in rotation around the vertical shaft. Another app for the level sensor allows users to quickly perform level measurements of the rotation axis of a shaft down to 0.001 deg. Both apps can be downloaded free of charge from this company’s app store. — Alignment Supplies Inc., Maumee, Ohio
