Sample ring kit model E, heavy, Ø 53 mm

This set allows for taking undisturbed samples in virtually all soil types to a depth of 2 metres and with a diameter of 53 millimetres, provided there are no rocks in its way. The samples can be taken from the surface, from the bottom of auger holes or from soil profile pits, both above and below the groundwater level.

The physical properties of soils are largely determined in the laboratory. Such studies usually require undisturbed soil samples, preferably with uniform dimensions. To meet these requirements, soil samples are taken in rings of a known volume and diameter.

Royal Eijkelkamp soil sample rings are made of seamless stainless-steel tube, smooth inside and out for as less as possible friction. The bottom of the ring has a cutting edge. The precise made dimensions and thus the volume content of the ring is exact, which makes it highly suitable for laboratory studies. The valve system can be cleaned easily.

Applications

• Water permeability
• Air permeability
• Weight by volume
• Density
• The soil-water-air relationship at field capacity
• The pore distribution
• The oxygen diffusion
• Determination of moisture content as various moisture tension levels, from which a pF-curve can be made
