CS230/CS231 Temperature Profiler
4
assembly and up to four optional external temperature probes. The rigid probe
assembly maintains the precise position of the temperature points within the
profile, while protecting the temperature sensors in all mediums.
The CS230/CS231 is suited for a wide variety of applications and
environments. The completely sealed probe assembly and external probes
permits the CS230/CS231 to be used in roadbeds, soils, and water (snow and
ice).
Examples of some applications include spring load adjustment, frost and
permafrost monitoring, soil and water temperature profiling, and snowpack
temperature profiling.
