HM 141 Hydrographs after precipitation

GUNT HM 141

Hydrographs After Precipitation system is designed for investigating the effect of precipitation on soils. It features a stainless steel experimental tank with a transparent splash guard for visual observation of the process. The precipitation device is equipped with two adjustable nozzles, allowing the user to control the precipitation area and quantity. The system includes a timer-controlled solenoid valve, which regulates the precipitation time, and a mobile sled carriage to distribute draining water to 17 chambers in the measuring tank.

A removable drain chamber or drainage pipe directs water drainage, and a separate flushing connection is provided for pipelines. The system also includes drip pans for rainwater retention, and a rotameter measures flow rates. This system is ideal for studying the behavior of soils under simulated rainfall conditions and is widely used in hydrology and soil science applications.
