Rupson Penetrometer With Automatic Timer Size 55 x 30 x 25 cms is a diagnostic tool to measure the extent and depth of subsurface compaction is a penetrometer, or soil compaction tester. It is used for determination of the needle penetration according to Astm and EN standards. The penetration depth of the needle is determined with a pulse type electronic measuring system. A penetrometer allows a weighted cone in contact with the food material to penetrate the surface under its own weight. The distance that it penetrates in a given time is the characteristic measure that is recorded.
