Soil Moisture Probes and Data Logger

By Sentek Technologies

EnviroSCAN Solo

EnviroSCAN Probe

The award winning EnviroSCAN probe is the flagship product of Sentek. It provides the user with great flexibility for precision monitoring of water and salinity at multiple depths in a soil profile.The EnviroSCAN probe first made its mark in irrigated agriculture, resulting in water savings of 30-50% and substantial yield and quality benefits. Today it is widely used in all forms of agriculture (irrigated and dryland), environmental applications, research and education, as well as turf, parks and gardens.The EnviroSCAN probe is the only commercially available product that allows for monitoring to great depths (up to 40 metres) using the same profiling probe.

EasyAG Probe

EasyAG Probe

The EasyAG probe is a slim-line, easy to install probe. Available in two fixed lengths of 30 cm (12 inches) and 50 cm (20 inches), the probes can be configured either with Soil Moisture sensors to measure volumetric water content only, or with TriSCAN sensors, to measure both volumetric water content and volumetric ion content (VIC).

The EasyAG probe is ideally suited to shallow rooted crops or where it is only necessary to measure no deeper than 50 cm.

Soil Solution Sampler

Soil Solution Sampler

The Sentek SoluSAMPLER is a soil solution sampler that draws moisture from the surrounding soil and stores it in an inert ceramic cup, awaiting collection and analysis. It is the ideal complement to the TriSCAN sensor, enabling precise site specific analysis of soil pore water salinity content.
Sentek SoluSAMPLER is available in two types, the difference is in the pore size of the ceramic cup:
  • Low Flow – suitable for most applications
  • High Flow – suitable for light texture and moist soils (for rapid sampling)
Diviner 2000  

Diviner 2000

Diviner 2000 is a portable and robust device measuring soil water over multiple depths (at 10 cm intervals) in the profile. Diviner 2000 consists of a probe and hand-held data logging display unit allowing the user to make onsite management decisions at up to 99 sites.The Diviner 2000 probe is available in 3 lengths, 0.7 metre, 1.0 metre and 1.6 metres making it ideal for a wide range of applications. The patented "Swipe and Go" technology means that Diviner 2000 does not need to be held at each individual depth in the soil profile. To take a reading the encapsulated capacitance sensor is simply swiped in and out of the access tube, measuring up to 16 depths in just a few seconds.

 Sentek Solo

Sentek Solo

Sentek Solo is a cost effective, continuous soil moisture and salinity monitoring solution. The Sentek Solo system consists of a battery powered, logging EnviroSCAN or EasyAG probe connected to a Solo Head Unit. Data is accessed in-field via the robust SoloPORTER™ or a notebook computer, and displayed in Sentek's IrriMAX software. Probes utilise the same interface as Sentek Plus, allowing for simple upgrade to wireless, web compatible communications.

Sentek Solo Head Unit:

  • One Sentek Solo Head Unit required per probe.
  • Sentek Solo Head Unit is connected to the probe via 3 metres of cable.
  • Powered by 4 removable "off the shelf" AA batteries.
  • Robust download port for in-field downloading.
PLUS Standard

PLUS Standard


Instantly Access All The Data You Need Without Going Back Into The Field.

  • 12-volt battery with solar panel for low maintenance self-charging.
  • Located in close proximity to the probe via 5 metres of cable.
  • Data transmission via cellular or satellite modem with antenna.
  • Front panel connectivity for local downloading (for data access if telecommunication services are unavailable).

Eliminate Guesswork With A Complete, Real-Time Picture Of Climate And Soil Conditions For Any Site.

  • Create a customised system using multiple inputs.
  • Connect up to 2 cabled soil moisture probes.
  • Add-on connections to temperature, rain and irrigation monitoring systems.
  • Data transmission via cellular or satellite modem.


A Cabled Solution With Up To 8 Probes Per Logger.

  • Provides flexibility in probe placement and data retrieval options.

  • Represents good value, as an alternative to maintaining wireless networks without the costs associated with telemetry at every sensor site.

  • In-field logger can connect up to 8 probes via cables.

  • High gain antenna can be positioned above tree canopies for improved range.

  • Solar powered for low maintenance.

  • Cable length up to 500 metres.

  • Data retrieval in-field using cable to laptop.

Important: Salinity and temperature sensors are not compatible with this option.
