• Extech VB300  3-Axis G-Force USB Datalogger

Records and times 3-axis shock and peaks

The VB300 is a G-Force datalogger which records and times 3-axis shock and vibration (acceleration) readings over its ±18g measurement range. This device will record 3-axis g-force and related peaks to provide a history of shock and vibration conditions. Complete with Magnetized/Bolt-on Mounting Base, 3.6V Lithium battery and Windows compatible analysis software.


  • Built-in 3-axis accelerometers record the time when shock occurs
  • Real time FFT Frequency and Time-Domain Vibration Analysis
  • Record storage, transport or operational data over time
  • USB interface for easy set-up and data download
  • Datalogs 112028 Motion Detection samples per axis, or 168042 Normal samples
  • Selectable X-, Y-, Z-axis or any combination (via software)
  • Selectable data sampling rate: 50ms to 24 hours
  • Manual and Programmable start modes
  • User-programmable alarm threshold
  • Long battery life
  • Complete with Magnetized/Bolt-on Mounting Base, 3.6V Lithium battery and Windows® compatible analysis software
