The Uni-T UT311A vibration meter is a compact device for monitoring the condition of machinery, measuring acceleration, velocity, and displacement of vibrations, with instant readings on a 2.4-inch TFT display.

The device features two frequency modes for acceleration:

• LO: 10 Hz - 1 kHz
• HI: 1 kHz - 15 kHz

This allows adjustment of measurement according to the nature of the equipment's operation.

The meter offers three main measurement methods:

• Acceleration (PEAK)
• Velocity (RMS)
• Displacement (P-P)

The separate frequency functions allow precise analysis of both slower and faster vibrations.

Main features:

• Clear TFT display with automatic rotation and backlight.
• Built-in flashlight for low-light conditions.
• Automatic power-off after 5 minutes for energy saving.
• 1350 mAh battery with up to 12 hours of operation.
• Charging via USB-C in approximately 3 hours.
• Weight about 191 g in ready-to-use configuration.
