Digital Precision Split Type Vibration Meter Tester Acceleration Sensor Gauge The product adopts piezoelectric type acceleration sensor and is suitable for measurement of conventional vibration of mechanical equipment. It can measure the vibration speed, acceleration, displacement and is widely used in mechanical manufacturing, electric power, chemical engineering, space flight and aviation and other fields. Features: Wide measurement range of acceleration: 0.1~199.9m/s2 peak. Adopts piezoelectric acceleration transducer transfer the vibration signal in to electrical signal, analyze the input signals, and show the vibration speed, acceleration, displacement. It can measure the environment temperature with 2 temperature units (℃ and ℉). LCD displays measurement result and conditions directly. Widely used in mechanical manufacturing, electric power, chemical engineering, space flight and aviation and other fields.

Don't use the device in the environment with explosive gas, steam and damp environment. When measurement is carried out near rotating part of the machine, operate carefully to avoid being pulled into the machine. Please use dry cloth to wipe the instrument case at the time of cleaning. Don't use corrosive detergents. Please take out the battery if the instrument is not in use for a long time or the storage temperature is higher than 50℃ to avoid corrosion to the instrument due to battery leakage. Please allow small size error due to manual measurement. Thanks for your understanding.This product is used to measure scenes with strong vibration and is not suitable for measuring weak vibration.
