In June 2008, Campbell Scientific removed the SEN13012 from our pricing system; some replacement parts remain available. (See the Ordering information.) This EasyAG II® TriSCAN probe had an SDI-12 interface and a 50-cm length. It determined VIC in sands and sandy loams. The SEN13012 was not suitable for clays or for stony soils that had an average stone size larger than 10 mm.
Sentek has changed the name of their water-content profile probe from EnviroSMART to EnviroSCAN.
