The device is a Class II laser measuring system. Two transmitters and two receivers are used to provide high accuracy speed measurement. Each part of the system is attached on a tripod and positioned on both sides of the impactor trajectory. This device can be used as a stand-alone system with its own display or with a laptop thanks to a specific serial connection.

MEASUREMENT • The accuracy is better than 0.2 %. • The display resolution is 0.01 km/h. • The maximum distance between transmitter and receiver is 10 meters. A corresponding calibration certificate is delivered.
