Mechanical Soil Auger: Sample ring kit, standard set to a depth of 2 m For soil sample rings Ø 60 mm. Soil sample ring kits are used for a variety of tests, including bulk density determination of soil. Soilsampleringkits The various sets are different from each otherbecause of the ring holder applied, the diameter ofthe rings connection, the selected and the samplingmethod. The sample sets with the postfix SA are applied tofill the soil sample rings in soft soils above thegroundwaterlevel. The samples can be taken on the surface, in boreholes or in profile pits. The open ring holder in thisset is fitted with a bayonet connection and is drivenintothesoilmanually. The set, among other items, contains: an open ringholder,anEdelman-andaRiversideauger,ahandle and extension rods, an aluminium casewithsoilsamplerings,variousaccessoriesandacarryingbag.
