Function description
This datalogger is engineered to record acceleration data of shock/vibration. This device
will record and time 3-axis vibrations and peaks to provide a history of shock/vibration
conditions. It is applied to the shock/vibration measurement such as transportation and
Shipping Applications, building vibration, endurance testing , etc.
•
Records 3-axis shock/vibration
•
Build-in accelerometers
•
Measures dynamic and static acceleration
