Berg offers portable options for measuring velocity including the CL5 w/Velocity Option - Krautkramer which is actually a thickness gauge with a built in velocity package. This device has the ability to determine the velocity of a material with a known thickness. Both the thickness and velocity can then be stored in the included data recorder and downloaded. Included with the device are a batter pack, AC power supply, carrying case, couplant sample, and other operating manuals and cards.
