A penetrometer is also used in longer professional cricket matches, to measure how the pitch is holding up over the course of a multi-day match. British horse racing courses have been required, since 2009, to report the readings obtained using a penetrometer, [ 1 ] on each day of a race meeting.
Symbol used in drawings Simplified version of a cone penetrometer. The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft ...

Full flow penetrometers (T-bar, ball, and plate) probes are used in extremely soft clay soils (such as sea-floor deposits) and are advanced in the same manner as the CPT. As their names imply, the T-bar is a cylindrical bar attached at right angles to the drill string forming what look likes a T, the ball is a large sphere, and the plate is ...
The Fall cone test, also called the cone penetrometer test or the Vasiljev cone test, is an alternative method to the Casagrande method for measuring the Liquid Limit of a soil sample proposed in 1942 by the Russian researcher Piotr Vasiljev (Russian: Пё́тр Васи́льев) and first mentioned in the Russian standard GOST 5184 from 1949.
Symbol used in drawings Standard penetration test N values from a surficial aquifer in south Florida.. The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil.
The lunar penetrometer was first developed in the early 1960s as part of NASA Langley Research Center’s Lunar Penetrometer Program. [7] At the time, immense pressures from the ongoing Space Race caused NASA to shift its focus from conducting purely scientific lunar expeditions to landing a man on the Moon before the Russians.
