Soil Data Probes

Sentek soil moisture probes feature capacitance-based technology which means soil profile measurements can be taken on a near continuous basis. Our probes offer high resolution measuring and enable 1/100th of a per cent change repeatability.

Unlike other brands, Sentek soil moisture probes allow user defined or site-specific calibration equations to be applied to each individual sensor. Our products take different soil types into account and can record more accurate information resulting in more timely responses, better land control, more valuable research and improved crop management. Our probes are also designed for undisturbed soil installation without the need for messy slurries. This ensures data’s scientific integrity and immediate useability.

To enhance the reliability and accuracy of your data, our patented TriSCAN® sensors can distinguish between soil water and salinity content. When our soil data probes are used with TriSCAN® sensors and Sentek’s IrriMAX advanced software system, the result is a comprehensive irrigation and fertilizer application management tool.


Our award-winning EnviroSCAN probe is the only commercially available product that can monitor soil moisture, salinity, temperature and humidity at depths up to 40 metres.
