How are the CS616 and CS625 improvements over the CS615-L?
The CS616 and CS625 meet European noise emission standards, which are stricter than U.S. standards.
The CS616 and CS625 period output is more linear than the CS615-L output.
The CS616 and CS625 operate over a wider range of soil types than the CS615-L.
The CS616 and CS625 have improved electrostatic discharge protection.
The CS616 and CS625 use surface-mount components with better frequency response, which is important for dielectric permittivity sensitive sensors.
A dedicated data logger instruction, CS616() in CRBasic and P138 in Edlog, makes CS616-L programming easier and produces a faster measurement. Similarly, a dedicated data logger instruction, PeriodAvg() in CRBasic, makes CS625-L programming easier and produces a faster measurement.
The CS616 and CS625 have less probe-to-probe variability than the CS615-L.
