Extech VB300 3-Axis G-Force USB Datalogger; Built-in 3-axis Accelerometers Record the Time When Shock Occurs; Real Time FFT Frequency and Time-Domain Vibration Analysis; USB Interface

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.
