Delta-T 25mm spiral auger, for dry sandy soils

The PR-AUG2 Spiral Auger (25 mm) is a specialized accessory tool for installing access tubes in dry, sandy soils where conventional augering can be problematic. In such soil conditions, standard augers often cause crumbling, collapse, or excessive widening of the augered hole, which leads to poor contact between the soil and access tube wall. The PR-AUG2 spiral design helps overcome these challenges.

Key Features

• Spiral Auger Design – The helical cutting edge is optimized to bite effectively into loose, sandy soil without collapsing the borehole.
• 25 mm Diameter – Matches the required size for preparing access tube pilot holes in sandy conditions.
• Durable Construction – Built from robust materials suitable for repeated field use.
• Compatible with Delta-T Kits – Designed as an add-on accessory for use with PR2 Profile Probe Augering Kits (starter or complete).

Function and Use

• The PR-AUG2 is manually rotated into sandy soil to create a narrow, stable pilot hole.
• It reduces the risk of conical widening (funneling) at the top layers of sandy soil—a common source of air gaps around access tubes.
• Ensures improved soil-to-tube contact, which is critical for reliable soil moisture measurements using PR2 Profile Probes.
• Used in combination with the stabilisation plate and insertion rod supplied in the main augering kits.

Applications

• Installation of access tubes for PR2 Profile Probes in dry, sandy soils.
• Field studies in agriculture, hydrology, irrigation management, and environmental monitoring.
• Ensures access tubes can be installed with the same reliability as in cohesive soils.

Ordering Information

• Product Code: PR-AUG2
• Description: 25 mm Spiral Auger (for dry sandy soils)
• Requirement: To be ordered in addition to the chosen Augering Kit (Starter or Complete).

Unique Advantages

• Specifically engineered for problematic sandy soil types.
• Provides straight, smooth holes where standard augers would fail.
• Extends the versatility of Delta-T Augering Kits by allowing access tube installation across more soil conditions.

The PR-AUG2 Spiral Auger (25 mm) is a vital accessory for researchers working in sandy environments. By providing stable pilot holes and ensuring close contact between access tubes and sandy soil, it safeguards the accuracy of PR2 Profile Probe soil moisture measurements. For laboratories and field researchers needing precise data in sandy conditions, the PR-AUG2 is an indispensable tool.
