This Vibration Tester is used for measuring periodic motion, check the imbalance and deflecting of moving machinery. Vibration is a reliable indicator of the mechanical health or condition of a particular machine or product. It is designed for measuring of various mechanical vibration. Build with rugged construction that allows long time usage. Features: Uses piezoelectric acceleration transducer to convert vibration signal Specially designed for easy on-site vibration measurement 3 accelerations in 1 sensor for 3-axis vibration measurement 3 same parameters in one display for 3-dimensional measurement or 1-dimensional measurement specified, showing 3 different parameters of velocity, acceleration, and displacement in 1 display Bearing condition monitoring function Individual high-quality accelerometer for accurate and repeatable measurements LCD digital display with backlight With Max. value hold and low battery indication Manual off at any time or auto power off Can communicate with PC computer for statistics and printing by the optional cable and the software for RS232C interface (not included in the set) AC output socket for earphones and recording for use as an electronic stethoscope ( Earphone is not included in the set) In accordance with ISO 2954, used for periodic measurements, to detect out-of-balance, misalignment and other mechanical faults in rotating machines Specifications: Display: 4 digit LCD backlit Sensor: 3-Axis Piezoelectric Accelerometer Axial Vibration: any one axis of X, Y, Z or 3 axes of XYZ Accuracy: 5 % of Reading + 2 digits Measurement range: Displacement: 0.001~4.000mm Equivalent Peak~Peak: 0.04~160.0 mil Acceleration: 0.1~400.0m/s2 Equivalent Peak: 0.3~1312ft/s2; 0.0~40g Velocity: 0.01~400.0mm/s True RMS: 0.004~16.00inch/s Frequency Range: Displacement: 10Hz~1kHz Acceleration: 10 Hz ~ 1k Hz 10Hz~10kHz Velocity: 10Hz~1kHz Metric Imperial Conversion Analogue Output: AC output 0~2.0V peak full scale (load resistance: above 10k) PC interface: RS232C (cable and software not included in the set) Operating conditions: Temperature: 0~50°C Humidity: Power Supply: 2 x 1.5V AA batteries Size: 130 x 76 x 32mm Weight: 340g (excluding battery) Set Includes: 1 x 3-Axis Vibration Tester 1 x Powerful rare earth magnet 1 x 3-Axis Piezoelectric Accelerometer 1 x Stinger probe (Cone) 1 x Stinger probe (Ball) 1 x English Operation Manual Carrying Case Standard Factory Packaging
