Sentek
Sentek Design, Develop, Manufacture, Support And Globally Distribute Best-In-Class Technology For Measuring And Managing Moisture, Salinity And Temperature Of Soil. Sentek Is The Proven Innovator To Understand Soil-Water-Plant-Atmosphere Dynamics And To Know What Actions To Take. Sentek Soil Probes Use Capacitance Based Technology To Provide Near Continuous Measurements Of The Soil Profile And Its Moisture Content. With High Resolution Measuring, They Also Enable 1/100th % Change Repeatability. Unlike other brands, Sentek soil moisture probes allow user defined or site specific calibration equations to be applied to each individual sensor. This ability to account for different soil types delivers even greater accuracy – meaning more timely responses, better land control, more valuable research projects and improved crop management. As well, they are designed for undisturbed installation without the need for messy slurries. By employing a patented measurement technique the TriSCAN® sensor is able to distinguish between soil water content and salt content. Coupled with Sentek’s IrriMAX software this becomes a comprehensive irrigation and fertigation management tool.

EnviroSCAN Probe

This award-winning technology, is the only commercially available product that allows for monitoring to great depths (up to 40 metres) using the same profiling probe. Get greater flexibility plus precision monitoring at multiple selected depths in each soil profile. EnviroSCAN probes are placed inside an access tube, which is fully sealed. The probe can be easily pulled up for maintenance or to replace parts if needed – providing a long field life. Available with either a flat cap for installation at ground level, or with a raised screw cap.
Features of the probe include:
  • Multiple sensors with adjustable depth placement (at 10cm increments).
  • Monitoring from shallow depths (0–10cm) to deep installations (up to 40 metres).
  • Flexible probe lengths, customized to suit the application (probe length adjustable in the field).
  • In-built probe orientation and depth settings to enhance sensor repeatability.
  • Full serviceability.
  • Flexible connectivity for wide range of data retrieval options.
  • Soil specific calibrations can be applied to individual sensors.

Drill & Drop probe

Easy Installation, Accurate Soil Moisture, Salinity, And Temperature Measurement. The Drill & Drop probe is fully encapsulated and can be completely buried, reducing the risk of machinery damage.

Measures soil moisture and temperature, with salinity optional useful for Vegetable crops, Fruit & Nut tree crops, Vines, Berries, research, and landscapes. The Drill & Drop probe is available in lengths from 30cm (12″) through to 120cm (48″) with sensors every 10cm or four inches.
It is also offered as a Single Point Sensor measuring 10.5cm or 4″ for SDI-12 loggers.

Drill-&-Drop-probe-Measurement
Probe Features
  • Undisturbed installation allows for measurement of truly representative soil profile, NOT slurry mix.
  • Buriable to any depth to allow working upper soil layer.
  • Durable low maintenance equipment will last for years.
  • Pre-calibrated sensors provide accurate readings in majority of soil types, with software that can make adjustments as needed.
  • Access near real-time soil profile data through online software IrriMAX Live – from any device.
  • Available with moisture, temperature and optional salinity sensors at every 10cm (4”) depth.
Probe-Features
Benefits
  • Ideal for seasonal use, such as monitoring vegetable crops, due to the fast and easy install and extraction techniques.
  • Reliable option for long-term use, as it can be installed and left untouched for many years.
  • Fast and undisturbed, slurry-free installation improves the validity of readings.
  • Combine soil moisture, salinity and temperature readings for a complete picture of what’s happening in the soil profile..

Diviner 2000

Take Readings In The Field – Instantly, Accurately, And Affordably. Patented ‘Swipe and Go’ technology gives you an accurate snapshot of that moment and allows soil moisture readings to be easily taken in seconds. Simply swipe the sensor in and out of the access tube and record data for up to 16 depths at 10cm intervals. Storing data for up to 99 sites, this is the probe you need for easy in-the-field monitoring and data transfer
Portable Soil Moisture Measurement.
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.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 simple swiped in and out of the access tube, measuring up to 16 depths in just a few seconds.

Sentek SoluSAMPLER

Incorporating SARDI Soil Water Extraction Technologies

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)
Sample Analysis
Samples of soil pore water are extracted from the ceramic cup using a syringe. Analysis of the water can then be carried out by:
Sentek-SoluSAMPLER
  • Portable Electrical Conductivity (EC) meter
  • Nitrate strips
  • Laboratory analysis
Benefits of Salinity and Nitrate Monitoring
Salinity and nitrate monitoring via soil solution sampling is important:
  • Saline water can reduce crop quality and yield
  • Irrigation efficiency may lead to an increased risk of harmful salt accumulation in the root zone
  • Measurement can detect salt before visual symptoms are seen
  • Using reclaimed, treated, or groundwater can potentially increase salt content
  • Nitrate levels are important for crop yields
  • Nitrate leaching into groundwater can have serious health consequences
DATA TRANSMISSION

Data Collected By Sentek Probes Can Be Retrieved Via A Range Of Options, And Transmitted To IrriMAX Software For Tracking And Analysis. Sentek Provides Flexibility And Convenience When It Comes To Accessing Probe Data. Get Manual Access While You Are In-Field To Check The Data, Or Monitor Conditions From Wherever You Need To Be, With Data Streaming To The Cloud And Accessed Via Sentek Software.
