The FullStop.
FullStop
The FullStop has been designed by Australia's CSIRO as a simple, low cost instrument to measure the passage of a wetting front. It helps you to "see" what is happening down in the root zone when you irrigate the soil. FullStops are buried in the root zone and pop up an indicator to show when the infiltrating water goes past. FullStop has no wires or batteries.The FullStop also collects a water sample from each wetting front so you can track fertiliser and salt movement.
This product can be used with the EC Meter and Nitrate Strips.

The GBSwitch.
GBSwitch
The GBSwitch can be connected to new and existing 24 Volt AC irrigation controllers to allow irrigation levels to be automatically adjusted according to the level of moisture in the root zone of the plants being watered.The GBSwitch is preset and does not need to be adjusted for different soil types. It doubles as both a rain sensor and a moisture sensor.
The GBSwitch is a Smartwatermark approved product Visit the Smartwatermark Web Site: www.smartwatermark.info/

The WET Sensor.
WET Sensor
Delta T Devices manufacture the WET sensor which measures Water content, EC and Temperature.The WET Sensor has crucial applications in precision horticulture and soil science research and is usable in both soils and growing substrates. It is exceptional in its ability to measure pore water conductivity (ECp), the EC of the water that is available to the plant.
At this stage the WET sensor is only available for use with a hand held reader; it is not a device which can be connected to a data logger.
