UNI-T UT311A Vibration meter

The Uni-T UT311A vibration meter is a compact tool for monitoring the condition of machinery. It measures vibration acceleration, velocity and displacement, and shows the results immediately on its 2.4-inch TFT display. Two frequency modes for acceleration measurement (LO: 10 Hz–1 kHz and HI: 1 kHz–15 kHz) let you match the measurement to the nature of the equipment being checked.

The three measurement methods, acceleration (PEAK), velocity (RMS) and displacement (P-P), allow you to assess both dynamic vibrations and the overall operating condition of a machine. The data hold function freezes readings on the screen, making them easier to read in less comfortable conditions.

Designed for field use, the meter features a clear TFT screen with automatic rotation and backlighting, so results stay readable whatever the orientation of the device. A built-in flashlight helps in low light, and automatic shut-off after 5 minutes reduces power consumption. The 1350 mAh battery is rated for about 12 hours of operation and charges via USB-C in around 3 hours. Weighing approximately 191 g, the unit ships with the short probe.
