The compact Uni-T UT312A vibration tester for quick machine condition checks measures acceleration, velocity, and vibration displacement and displays values on a 2.4" TFT screen. With two acceleration frequency modes (LO/HI), Data Hold, automatic screen rotation, a built-in flashlight, and USB‑C charging, it is ideal for field inspections and routine industrial diagnostics.
Uni-T UT312A is a portable vibration measuring instrument designed for condition monitoring in industry and maintenance. It enables quick vibration evaluation and early detection of bearing wear, imbalance, or mechanical looseness. The clear TFT display with automatic rotation makes it easy to read values in any position.
Key features and benefits:
- 3 measurement modes: acceleration (PEAK), velocity (RMS), and displacement (P‑P)
- Two acceleration frequency modes: LO 10 Hz–1 kHz and HI 1 kHz–15 kHz for more accurate analysis of different vibration types
- Data Hold to freeze the measured value on the display
- Auto power-off after 5 minutes to save energy
- Built-in flashlight for work in low-light conditions
- Rechargeable Li‑Ion battery with approx. 12 hours of runtime and USB‑C charging (approx. 3 hours)
