Uni-T UT312A Vibration Tester

The Uni-T UT312A Vibration Tester is a compact machine condition monitoring device that measures vibration acceleration, velocity and displacement with instant readings displayed on a 2.4-inch TFT display. The device operates in two acceleration frequency modes (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. With its compact design, auto-rotating display, built-in flashlight and USB-C rechargeable battery, the UT312A is ideal for field inspections and routine diagnostics of industrial equipment.

Measurements tailored to different applications

The UT312A offers three key measurement methods: acceleration (PEAK), velocity (RMS) and displacement (PP), allowing you to assess both dynamic vibration and the overall operating condition of the machine. Separate frequency modes for acceleration (LO and HI) allow for more accurate analysis of slower and faster vibrations, rather than using a single generalized range. The Data Hold function allows you to freeze the result on the screen, making it easier to read in less convenient conditions.

Ease of use and portability

Designed for field use, the device features a clear TFT display with auto-rotation and backlighting, improving visibility of results regardless of orientation. A built-in flashlight helps in low light conditions, and an 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 approximately 3 hours. The weight of approximately 364 g includes the device with a short probe, so it is in a ready-to-use configuration.
