Despite its simplicity, the apparatus has a high degree of sensitivity and may be used for student project work as well as for demonstration purposes. The Demonstration Lysimeter consists of three 300mm diameter containers in which may be placed any soil type and a variety of crop types grown. Each container can then in turn be placed on a hydraulically mounted plate which is used to monitor system weight changes arising from evapotranspiration.

Equilibrated soil samples placed on the sand are then subjected to a known variable suction range of 0- 800mm of water. These equipment consists of a free-standing circular tank filled with saturated sand (not supplied). The suction is applied by means of a buried porous pipe and an associated sliding control chamber. In order to maintain the suction an uninterrupted low volume water supply is required.

The Drain Permeameter is suited for use both as a teaching and demonstration tool and for laboratory testing and research. A removable base section is provided into which the filter material to be investigated is placed. The equipment consists of a 100mm diameter transparent column which may be filled with any soil type.
The apparatus is supported on a sturdy metal frame and may be conveniently placed on a laboratory bench close to a water supply and drain. Water is added to the column under a constant head and permeating water and soil is collected at the base. The discharge from the drain can be monitored to assess the efficiency of the filter material.
The Rainfall Simulator consists of a metal frame that supports the spray head assembly. In use, water is pumped from the holding tank via a control valve to the spray nozzle. The unit may be placed directly on the ground for field studies or used with its accessory tray for laboratory experiments. Water from the spray nozzle is interrupted by a horizontal rotating disc driven by a variable speed motor. For use in field or laboratory electrical and water supplies are required. Adjustable width apertures in the disc allow some water to pass and the remainder is recirculated via the tank.

Measurement of rates of water penetration into the soil is aided by a grid on the tank front. The equipment is self-contained with a sump tank, pump and flowmeter fitted behind the tank. Water may be discharged along the soil surface or directed to twin drip nozzles to demonstrate trickle irrigation.
Removable end plates allow soil samples to be changed quickly and easily.
The apparatus consists of a narrow transparent fronted tank which may be partially filled with any soil type. It is supported on a bench mounted frame.
