EnviroSCAN探头提供了土壤含水量剖面测量,可用于灌溉控制或其它水运移系统中。测量范围从烘干到水饱和。探头在多个深度位置测量土壤含水量,易于安装。由Campbell Scientific提供的安装工具使得安装对土壤扰动最小。建议EnviroSCAN用于更高精度的研究测量、测量深度大于80 cm,或者是石质土壤。可定制,按用户指定的深度增加测量点的数目。
EnviroSMART探头已经被重命名为EnviroSCAN。
EnviroSCAN探头由Sentek生产,提供了土壤含水量剖面测量,可用于灌溉控制或其它水运移系统中。测量范围从烘干到水饱和。探头在多个深度位置测量土壤含水量,易于安装。由Campbell Scientific提供的安装工具使得安装对土壤扰动最小。
建议EnviroSCAN用于更高精度的研究测量、测量深度大于80 cm,或者是石质土壤。可定制,按用户指定的深度增加测量点的数目。标准配置的最大测量深度为2 m;如果特别供应,也可实现更深深度的测量。
