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.

Measurement	volumetric water content	Pore water conductivity	Temperature
Accuracy	± 0.03 m3.m-3 (1%)	see graph below	± 1.5°C
Soil moisture measurement range	Full accuracy over: 0 to 1 m3.m-3	see graph below	0 to 50°C
Salinity range	0 to 300 mS.m-1
	Supplied with extended range calibrations which should be used for readings between 300 to 500 mS.m-1
Temperature range	-5 to 50°C
Output	Serial TTL data providing permittivity, bulk conductivity and temperature, from which water content and pore water conductivity are calculated
Power requirement	6-10 V, ~38 mA for 2.5s
Environmental	IP68
Sample volume	~500 ml
	Sample volume is weighted towards soil immediately surrounding the rods
Dimensions and weight	Overall: 120 x 45 x 13 mm  Rods: 68 mm x 3 mm diameter  Outer rods 68mm x 3.0 mm dia Central rod 65 mm x 5.0 mm dia Weight: 0.1 kg
Sensor calibrations	Sensor calibrations supplied in WET Sensor EEPROM Recalibration advised every 3 years (dependent on use)
Soil calibrations	Generalised Mineral ,Organic, Sand and Clay calibrations are supplied, specialist calibrations are available for horticultural substrates (please enquire at sales@delta-t.co.uk for more information) .

Channel science and technology has been dedicated to the teaching, scientific research and the sales, research and development of applied instruments in the fields of soil, plants, environment, hydrology, meteorology and animal physiology, ecology and environmental hydrology for many years.
