Uni-T UT311A Vibration Meter

Uni-T UT311A Vibration Tester

The Uni-T UT311A Vibration Tester is a compact device for monitoring the condition of machines that measures acceleration, speed and movement of vibrations with instant readings displayed on a 2.4-inch 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 customize the measurement based on the nature of the equipment's operation. Its compact design, self-rotating screen, integrated flashlight, and USB-C rechargeable battery make the UT311A ideal for field inspections and

Tailor-made measurements for various applications

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

Ease of use and portability

The device has been designed for field use, which is why it has a clear TFT screen with automatic rotation and backlighting, improving the visibility of the results regardless of orientation. The integrated flashlight helps in low light, and the automatic shutdown after 5 minutes reduces energy consumption. The 1350 mAh battery offers up to about 12 hours of operation, and charging via USB-C takes about 3 hours. The weight of about 191 g includes the device with the short probe, i.e. in a ready-to-use configuration.
