Although the SEN17012 is retired, some replacement parts remain available. (See the Ordering information.) This EasyAG II® TriSCAN probe had an SDI-12 interface and an 80-cm length. It determined VIC in sands and sandy loams. The SEN17012 was not suitable for clays or stony soils where the average stone size was larger than 10 mm.
Sentek has changed the name of their water-content profile probe from EnviroSMART to EnviroSCAN.
