Double Ring Infiltrator (ASTM D3385) – Complete Kit
The Double Ring Infiltrator Kit is a professional instrument designed for direct field measurement of soil infiltration rate. The system is fully compliant with the international standard ASTM D3385, ensuring accuracy and repeatability of the data collected.
This test method represents a practical and economical solution for geologists, agronomists and environmental technicians who need certain parameters on the permeability of the soil.
Composition of the Kit
The ready-to-use kit includes the following components:
- Double Reinforced Infiltration Ring: 12″ and 24″ (30 cm and 60 cm) diameters with 20″ (50 cm) height – Code AMS-65102 .
- Dedicated Stop Plate: specific for the 24″ (60 cm) ring to facilitate driving – Cod. AMS-65104 .
Application Areas and Uses
Determination of the infiltration rate using the ASTM D3385 method is critical to:
- Liquid disposal: design of wastewater dispersion systems and septic tanks.
- Hydraulics and drainage: evaluation of the efficiency of urban/extra-urban percolation and drainage.
- Agriculture: determination of irrigation needs and water management.
- Hydrogeology: studies on the recharge of aquifers and dispersions in canals or reservoirs.
High Quality Construction Features
The rings are made to withstand intensive use on the construction site:
- Material: Laminated mild steel with a thickness of 16 gauge (approx. 1.5 mm).
- Finish: High-quality, weather-resistant powder coating.
- Ecology: Non-toxic and environmentally friendly material, ideal for testing agricultural or sensitive soils.
- Impact plate included: It allows manual or hammer insertion even in compact soil, protecting the edge of the rings.
