The CS635 consists of three pointed 15 cm long rods that can be used in high electrical conductivity soils (maximum soil bulk electrical conductivity 3.5 dS/m).
The CS63 and CS30 probes are similar, differing only with the cable used. They represent our mid-range TDR probes, providing a larger sample volume than the CS640/CS645 but not as large as the CS605/CS610.
