Description

The Armfield Demonstration Infiltration Apparatus provides a simple but effective laboratory demonstration of infiltration processes, which are fundamental to any form of irrigation. Each cylinder features a graduated scale so that observations may be quantified. Each cylinder incorporates an air breather and a perforated base plate to facilitate drainage without undue soil loss.
