        UT-312 vibration meter is a split portable vibration measurer which consists of acceleration 
sensor and digital measurement display circuit. It is mainly used to measure vibration 
displacement, speed (or intensity) and acceleration of mechanical equipment. Current status 
(such as excellence, notice or danger) can be determined for equipment (such as fan, pump, 
compressor and motor, etc) by above measuring data according to enterprise & machine 
standards by comparing with national metrological verification regulations of JJG 676-2000 
working vibration meter. 
       Such instrument has measuring value locking, low-voltage prompt and automatic shutdown 
functions. With advantages such as wide measurement scope, simple operation and 
convenient carrying, it can be used for patrol detection of equipment vibration in power, 
metallurgic and petrochemical industries widely so it is an ideal tally instrument.
