Mini Disk Infiltrometer

The Mini Disk Infiltrometer is a compact, field‑ready instrument for measuring the unsaturated infiltration rate and hydraulic conductivity of soil under controlled suction. Designed for both field and laboratory use, it makes hydrology and soil‑science testing significantly simpler and more portable. The device uses a sintered stainless‑steel disk that contacts the soil surface, with an adjustable suction chamber (Mariotte/ bubble tube) above, enabling the measurement of infiltration under specified negative suction (tension) conditions. This enables hydrologists, soil scientists, agronomists and field engineers to quickly gather data on how water moves into soil under near‐field conditions.

The compact size, minimal water requirement and simple operation make it particularly suitable for remote field sites, classroom demonstrations, and large‐scale spatial surveys where traditional tension infiltrometers would be too bulky or complex.
