Soil sample rings

Soil sample rings are stainless steel rings made of seamless tubes, smooth inside and out. The bottom of the ring has a cutting edge. The dimensions, and thus the volume content, of soil sample rings are exactly known, which makes them highly suitable for laboratory studies. With soil sample rings undisturbed samples can be taken. Soil sample rings are available with standard diameters 53, 60, 84 mm and 103 mm.

These are then used for, for example:

• moisture content at various moisture tensions, from which a pF-curve can be made.
  
• water permeability.
  
• air permeability.
  
• weight by volume.
  
• density.
  
• soil-water-air relationship at field capacity.
  
• pore distribution.
  
• oxygen diffusion.

Soil sample rings are transported in special aluminum cases, strong and resistant against humidity and heat.

Key Advantages

• Available in various diameter
  
• Accurately machined stainless steel rings
  
• Rings have a very accurate volume
