UNI-T UT311 UT-311 Portable LCD Vibration Analyzer Tester Meter Vibrograph  Vibrometer with Acceleration Sensor in One UT311/UT312 vibration meter UT310 series portable vibration meter is an integrated pocket and hand-held vibration meter composed of piezoelectric acceleration sensors and digital display circuits. It is mainly used for measuring the vibration displacement, velocity (intensity), and acceleration of mechanical equipment. UT310 series products can be divided into integrated, split, and multi-functional intelligent types for your choice based on the connection method between the vibration sensor and the host computer. Fully meet the conventional measurement of mechanical equipment, especially vibration measurement in rotating and reciprocating machinery. It is widely used by on-site equipment operation and maintenance personnel to monitor equipment status, timely identify problems, and ensure normal and reliable operation of equipment.
