Why use to Fluke 931 Tachometer ?

The Fluke 931 Tachometer is a compact and reliable digital tachometer designed for easy, accurate measurement of rotational speed and RPM (revolutions per minute) in industrial, maintenance, and mechanical applications. This versatile tool is ideal for assessing the speed of motors, conveyor belts, fans, and other rotating machinery to ensure optimal performance and prevent system malfunctions.

With both contact and non-contact measurement modes, the Fluke 931 provides flexibility for a wide range of tasks. The contact mode allows for direct measurement using the included reflective tape, while the non-contact mode uses a laser to measure the RPM from a distance. The large, easy-to-read digital display provides precise readings in RPM, m/min, or ft/min, with high accuracy and resolution, making it suitable for a variety of environments.

The Fluke 931 features a backlit display, making it ideal for use in low-light conditions. It also includes a data hold function, which allows users to freeze the reading on the display for easier recording. The auto power-off feature helps conserve battery life during long measurement sessions.

With its robust design, the Fluke 931 is built to withstand the rigors of daily use in the field. Whether you’re performing routine maintenance, troubleshooting equipment, or conducting system diagnostics, the Fluke 931 provides accurate, consistent results.
