Features:Used for measuring periodic motion, to check the imbalance and deflecting of moving machinery.Is specifically designed for present measuring various mechanical vibration. So as to provide the data for the quality control, run time and equipment upkeep.It use the high-performance acceleration meter, realize the repetitiveness and accurate measurement.It has the function of testing axle bearing situation.Vibration meter(also called also called vibration severity) uses Piezoelectric Acceleration Transducer transfer the vibration signal in to electrical signal, analyze the input signals, and show the Acceleration, speed, shift of the vibration.It is widely used in the lines of Power, petrochemical, machinery manufacturing, metallurgy, vehicles, etc.Multifunctional, with Temperature Measurement, Auto Switch Range, Backlight, Auto Power off.Specification:Vibration Pickup:Piezoelectric Ceramic Accelerometer(shear-type)Acceleration:0.1~199.9m/s²Velocity:0.1~199.9m/sDisplacement:0.001~1.999mmAcceleration Frequency Range: 10HZ~1KHZ(LO); 1KHZ~15KHZ(HI)Velocity Frequency Range:10HZ~1KHZDisplacement Frequency Range:10HZ~1KHZAccuracy:±5%H±2digitsPower: 9VDC battery（not included）Size:70 * 35 * 100mm / 2.8 * 1.4 * 3.9inWeight: 1000 g / 35.3 oz(approx.)Package list:1 x Vibration Analyzer Tester（batterynot included）1 x instructions3 x probe1 x Aluminum case1 x Split probe
