The SEN13512 was retired in July 2008. This EasyAG TriSCAN probe had an SDI-12 interface and an 50-cm length. It determined VIC in sands and sandy loams. The SEN13512 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.
