The VC4000 accelerometer is an instrument DJS Associates uses to measure vehicle brake testing and acceleration.

Its accuracy can be demonstrated by comparing the data to any reliable method that measures speed, distance, time or G-force. The accelerometer can be used for a variety of different applications including:

• Traffic accidents/collisions
• Automotive engineering
• Bus testing
• Race car testing
• And many more…

The accelerometer accurately measures G force within 1%, speed within 1 mph, distance within 1% and time within .01 second.
