The UNI-T UT311A is a compact, palm-sized instrument designed to bring professional-grade vibration analysis into the hands of every technician and engineer. Encased in a durable, lightweight housing barely larger than a smartphone, the UT311A balances portability with robust construction, allowing it to withstand the rigors of daily industrial use. Its integrated piezoelectric sensor is tuned for high sensitivity, capturing subtle oscillations in machinery with impressive precision. The operator is greeted by a crisp 2.4-inch TFT color display that automatically rotates to stay upright regardless of orientation, ensuring measurements remain legible even in tight spaces or awkward angles.
From the moment it’s powered on, the UT311A exudes intuitive simplicity. A single-handed grip positions the thumb naturally over the primary controls, while minimal button presses transition seamlessly between acceleration, velocity, and displacement modes. Behind this ease of use lies sophisticated signal processing electronics that filter out noise and present only the most relevant data. In bright sunlight or dimly lit engine rooms, the built-in backlight and onboard flashlight guarantee that the display and measurement point are always clearly visible.
Ergonomics extend beyond the user interface. The UT311A’s battery is thoughtfully integrated to provide up to twelve hours of continuous operation on a single charge, and the inclusion of both long and short probes means technicians need carry only one device to cover a wide range of measurement scenarios. Magnetic mounting accessories can be affixed to permanent fixtures for hands-free monitoring, further reducing setup time and operator fatigue.
By merging precision sensing, streamlined controls, and rugged portability, the UNI-T UT311A transforms vibration inspection from a specialized task into a routine check that can be performed by maintenance teams of any size. Its design philosophy champions speed and simplicity without compromising accuracy, making it an indispensable tool for ensuring the smooth operation of pumps, motors, gearboxes, and other rotating machinery.
Features:
- High-sensitivity piezoelectric sensing: Delivers crisp, responsive readings by converting even very slight mechanical oscillations into clean electrical signals, so subtle faults won’t slip past your inspection.
- Three-mode vibration analysis: Instantly toggle between acceleration, velocity and displacement views, allowing you to target the signature most relevant to the machine fault you’re chasing.
- Auto-rotatable color display: The 2.4″ TFT screen reorients itself as you turn the instrument, keeping readouts upright and legible whether you’re hanging upside-down inside a panel or working at odd angles.
- Built-in LED flashlight: Integrated illumination lets you pinpoint the exact measurement point—even in shadowed or cramped environments—without juggling a separate torch.
- Interchangeable probe system: Ships with both long-reach and stub probes; swap them out on the fly to access confined or recessed test points without changing instruments.
- Auto power-off & data-hold: Conserves battery life by shutting down after inactivity, yet lets you freeze the current reading at the push of a button for hands-free documentation or remote viewing.
- On-screen battery indicator: Continuously displays remaining charge, so you know at a glance when a recharge is needed—no more surprises mid-inspection.
- Rugged, pocket-sized housing: Encased in a tough, palm-friendly shell that’s light enough to carry all day yet durable enough for harsh factory floors.
- Multilingual interface: Menu and prompts are offered in eight major languages, making it easy for global teams to operate without needing a translator.
- Universal USB-C charging: Recharges quickly from any modern charger or power bank—eliminating the need for proprietary adapters and keeping downtime to a minimum.
