The decelerometer can simply be placed on the floor of the vehicle.

Accelerate the vehicle to a test speed of 20 - 40 km/h, disengage the clutch and brake the vehicle until it comes to a standstill. The measurement values appear instantaneously on the display and print out.

The deceleration measurement can be done easily and quickly using our battery-driven decelerometer without any set up time on the vehicle required.Optionally, pedal force, traction and pressure sensors (pneumatic/hydraulic) can be connected. All measurement values are recorded simultaneously with the deceleration measurement and can be graphcially printed on the integrated printer. All data can be transferred to a PC for future record keeping of measurements.

Brake Testing- mobile and quick

simple measurement procedure...
