EnviroSCAN Screw Cap


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.
