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.
Features include:
Multiple sensors with flexible depth placement (at 10 cm increments)
Monitoring from shallow depths (0 - 10 cm) to deep installations (> 40 metres)
Length of probe customised to suit the application (probe length adjustable in the field)
Up to 16 sensors on one probe (moisture or moisture/salinity)
In-built probe orientation and depth settings to enhance sensor repeatability
Full serviceability
Flexible connectivity for wide range of data retrieval options

Probe Sealing
The bottom of the access tube is typically sealed using a double-ringed expandable rubber bung, providing 2 sealing points and preventing underground moisture from entering the tube. A slurry cap is also available.
The top of the access tube is sealed with 2 different top cap designs, depending on application.
EnviroSCAN Screw Cap
Top cap protrudes above the soil surface
Easy to find and readily accessible
Tightly sealed with a rubber O-ring
Simply un-screws, giving easy access to the probe for servicing
EnviroSCAN Flat Cap
Allows for the probe to sit flush with the ground surface
Water-tight, 3 point sealing design
Provides ready access to the probe for servicing
Avoids potentially costly damage from machinery

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.
Features include:
multiple sensors at fixed depths
EasyAG 30 - sensors at 10cm, 20cm, 30cm
EasyAG 50 - sensors at 10cm, 20cm, 30cm, 40cm, 50cm
In-built probe orientation and depth settings to increase sensor repeatability
Slim-line probe
Access Tubes
Both types of probes are installed into customised access tubes to allow for:
improved sensor accuracy through precise wall thickness and diameter of access tube
protection of sensors by avoiding direct soil contact
specific sealing to ensure long-term operation
full in-field serviceability without impacting on data integrity
minimum soil disturbance during installation and hence measurement of an undisturbed soil profile
