UNI-T UT311 Vibration Tester

From the shop's description

UNI-T UT311 Vibration Tester The UNI-T UT311 is a compact handheld vibration tester engineered to precisely measure multiple vibration parameters, including acceleration, velocity, and displacement in rotating and reciprocating machinery. It offers technicians an integrated solution for monitoring equipment health and operational status, helping detect mechanical issues before they escalate. In a single device, users can switch seamlessly between key measurement modes all of which support the evaluation of vibration magnitude across relevant frequency bands. This modular design ensures convenience, especially when inspecting industrial components or maintenance-critical equipment. Despite its small size just 185 × 68 × 30 mm and weighing around 230 g with battery the UT311 packs substantial functionality. Its red-and-grey casing houses a 9 V battery for over 20 hours of continuous operation. The unit comes in a toolbox-style package and includes an English manual, making it practical, durable, and user-friendly in the field. Feature: Highly accurate measurements of acceleration, velocity, and displacement. Switchable vibration frequency characteristics for targeted diagnostics. Auto power-off and low battery indication to preserve energy. Data hold function (automatically captures reading when releasing the measure key).
