This device is used to determine the workability and degree of compaction of fresh concrete after being placed in the forms. The operation is very simple: insert the tester  into the concrete up to the level of the disc, after 60 seconds, a measuring rod in lowered onto the surface of the concrete and the K-slump is read directly on a scale. It can be used for in-situ measurements or inside test moulds and forms. Results can be correlated against the slump test. The calibrated hollow tube has a dia. of 20 mm.
