CS659含水量探头用于Hydrosense II系统,它的探针长度为 12 cm;另一种探头CS658的探针长度为 20 cm。当与HS2 Hydrosense II读表一起订购时,CS659为其选项 -12。CS659还可作为备件订购。
CS659设计往硬土中插入,或从其中移除。传感器使用卡套螺母将探针坚固在探头基座上。模塑的紧握塑料将线缆连接到基座上。

The CS659 is used with the Hydrosense II soil content system only. (The CS659 is designed for use with the HS2 but not with the HS2P.) The rods of the CS659 and CS658 are not interchangeable.

Because of the thread type used for the two sensors/rods, it is physically impossible to interchange the rods.
If measurements are needed for both depths, both the CS658 and CS659 must be used.
