CS230 Temperature Profiler
2
The CS230 is suited for a wide variety of applications and environments. The
completely sealed probe assembly and external probes permits the CS230 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.
The purpose of the SGB3 is to provide adequate surge protection for the CS230
Temperature Profiler. The case of the SGB3 is suited for mounting to a back
plate with 1 inch on center spacing.
