Here's a brief overview of the PRUFTECHNIK Shaftalign OS3 Laser Shaft Alignment tool:

1. Laser Technology: The tool uses a laser to accurately measure the alignment between shafts. The laser system typically consists of a transmitter and a detector.  Laser Type: Semiconductor laser diode

2. Display Resolution: 320 x 240 pixel

3. User Interface: The Shaftalign OS3 often features an intuitive display interface, showing graphical representations of the alignment condition, guiding the user through the alignment process.

4. Single Laser/Dual PSD: This allows for high precision with quick measurement and alignment processes.

5. Live Trend: The tool can monitor machine positional changes in real-time, making it useful for settling tests and to verify if machinery moves during operation.

6. Tolerance and Targets: Users can set their alignment tolerances. Once machines are within these tolerances, the device provides a clear indication that alignment is successful.

7. Rugged Design: Designed for industrial environments, the Shaftalign OS3 is typically durable, resistant to common chemicals, dust, and water splashes.

8. Documentation: The device may have capabilities to store measurement data, which can then be transferred to PCs or other devices for reporting and analysis.

9. Soft Foot Check: Ensures that the machine's feet are evenly supporting the machine, which is critical for accurate alignment and smooth machine operation.
