UNI-T UT312A High-Precision Digital Vibration Meter | Acceleration, Velocity & Displacement Tester | 2.4-Inch TFT Rotating Screen

The UNI-T UT312A High-Precision Digital Vibration Meter is a compact and professional handheld vibration tester designed to measure the vibration condition of mechanical equipment. It measures acceleration, velocity, and displacement, helping maintenance professionals identify abnormal vibration and assess the operating condition of motors, pumps, fans, compressors, gearboxes, bearings, and other rotating machinery.

Equipped with a high-sensitivity vibration sensor, high and low frequency acceleration measurement modes, multiple probe options, and a clear 2.4-inch TFT color display with automatic screen rotation, the UT312A provides convenient operation during equipment inspection and maintenance.

The UNI-T UT312A also features a 1350mAh rechargeable lithium battery with Type-C charging, approximately 12 hours of battery duration, data hold, battery indication, LCD backlight, and a built-in flashlight. Its compact handheld design makes it practical for routine vibration monitoring and preventive maintenance in industrial environments.

What Is the Purpose of the UNI-T UT312A Digital Vibration Meter?

The primary purpose of the UNI-T UT312A vibration meter is to measure mechanical vibration and help determine whether equipment is operating normally. Excessive vibration can indicate issues such as imbalance, misalignment, looseness, bearing wear, mechanical deterioration, or other developing equipment problems.

The UT312A measures three important vibration parameters: acceleration, velocity, and displacement. This allows technicians to evaluate machine vibration from different measurement perspectives and use the results as part of a preventive maintenance program.

It is especially useful for patrol inspection, routine equipment checks, predictive maintenance, troubleshooting, and vibration condition monitoring in industrial facilities.

How to Use the UNI-T UT312A Vibration Meter

1. Charge the meter: Fully charge the rechargeable lithium battery using the supplied Type-C charging cable before extended inspection work.
2. Power on the instrument: Turn on the UT312A and allow the display and vibration sensor to initialize.
3. Select the measurement parameter: Choose acceleration, velocity, or displacement according to the equipment inspection requirement.
4. Select the appropriate acceleration mode: Use the high or low frequency acceleration mode when applicable to the vibration being investigated.
5. Choose the probe: Select the appropriate long or short probe according to the measurement location and accessibility.
6. Position the sensor: Place the probe firmly against the machine or measurement point to obtain a stable vibration reading.
7. Read the measurement: Observe the vibration value on the 2.4-inch TFT color screen.
8. Use the magnetic sucker when suitable: The supplied U-type magnetic sucker can be used for convenient attachment to compatible metal measurement surfaces.
9. Use Data Hold: Activate the data-hold function when you need to retain a measured value on the display.
10. Record and compare results: Compare measurements from different inspection points or previous inspections to help identify changes in machine vibration.
11. Turn off after use: Switch off the instrument when the inspection is complete. The automatic power-off function helps conserve battery power when the meter is not operated.
