Uni-T UT311A Vibration Tester

The Uni-T UT311A Vibration Tester is a compact machine health monitoring device that measures vibration acceleration, velocity, and displacement with instant readings displayed on a 2.4" TFT screen. The device operates in two frequency modes for acceleration (LO: 10 Hz–1 kHz and HI: 1 kHz–15 kHz), allowing you to tailor the measurement to the nature of the equipment’s operation. Its compact design, auto-rotating screen, built-in flashlight, and USB-C rechargeable battery make the UT311A ideal for field inspections and routine diagnostics of industrial equipment.

Measurements tailored to various applications

The UT311A offers three key measurement methods: acceleration (PEAK), velocity (RMS), and displacement (P-P), allowing you to assess both dynamic vibrations and the overall operating condition of the machine. Separate frequency modes for acceleration (LO and HI) allow for more precise analysis of both slower and faster vibrations, rather than using a single generalized range. The Data Hold function allows the result to be frozen on the screen, making it easier to read in less convenient conditions.

Ease of Use and Portability

The device was designed for field use, which is why it features a clear TFT screen with automatic rotation and backlighting, improving the visibility of results regardless of orientation. The built-in flashlight aids in low-light conditions, and the automatic shut-off after 5 minutes reduces power consumption. The 1350 mAh battery provides up to approximately 12 hours of operation, and charging via USB-C takes about 3 hours. The weight of approximately 191 g includes the device with the short probe, i.e., in a ready-to-use configuration.
