The Fluke 831 laser shaft alignment tool enables quick and complete alignment of rotating machinery without requiring advanced training or complex programming. Its intuitive guided user interface leads technicians through the alignment process step by step, ensuring consistent, accurate results every time.

The single coaxial reflected laser beam sensor simplifies setup and delivers fast, precise measurements. For vertical machines, the 831 supports up to 8 measurement points, allowing technicians to achieve precision alignment even in challenging configurations. The 90° roof prism reflector ensures reliable signal return.

Misalignment is a leading cause of premature bearing and seal failure, energy waste, and unplanned downtime. By making alignment fast and easy, the Fluke 831 enables maintenance teams to align every machine they repair or overhaul, potentially saving thousands of dollars per year in reduced downtime and replacement parts.

The instrument is powered by a high-performance Exynos processor with 4GB RAM and 64GB flash memory, providing fast response and ample data storage. Built-in Wi-Fi, Bluetooth, and NFC enable seamless connectivity, while the IP68 rating ensures survival in harsh industrial environments.
