EnviroSCAN Probe Reliable Performance 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. Features of the probe include: Probes are inserted into customised 56.5mm diameter access tubes to allow for: The EnviroSCAN probe is widely used in all forms of agriculture (irrigated and dryland), environmental applications, research and education, as well as turf, parks and gardens. EnviroSCAN is the only commercially available product that allows for monitoring to great depths (up to 40 metres) using the same profiling probe. • 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, customised 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. • 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. Installation of access tubes is carried out using specialised tools to ensure minimum soil disturbance during installation and hence measurement of an undisturbed soil profile. • Soil specific calibrations can be applied to individual sensors. Access Tube EnviroSCAN EnviroSCAN Screw Cap

Probe Sealing The bottom of the access tube is sealed using any of: 1. A Double-ringed expandable rubber bung, providing 2 sealing points and preventing underground moisture from entering the tube, or 2. A slurry cap, which is glued in place, or 3. The solid, sealed FAST1 base with a cutting edge. • Allows for the probe to sit flush with the ground surface. • Top cap protrudes above the soil surface. • Water-tight, 3 point sealing design. • Easy to find and readily accessible. • Provides ready access to the probe for servicing. • Tightly sealed with a rubber O-ring. • Avoids potentially costly...
