The CS230 temperature profiler uses SDI-12 digital technology for simple integration. SDI-12 does away with analog measurement inaccuracies and susceptibility to electrical noise. The CS230 consists of a rigid probe 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 for the long-term. The CS230 is suited for a wide variety of applications and environments. The completely sealed probe assembly and external probes permit the CS230 to be used in roadbeds, soils, and water (snow and ice). Applications where the CS230 is used include spring-load adjustment, frost and permafrost monitoring, and soil  and water temperature profiling.
