The CR1000Xe provides measurement and control for a wide variety of applications. Its reliability and ruggedness make it an excellent choice for remote environmental applications including stations for hydrology and meteorology (HydroMet), solar resource assessment and monitoring (SRA/SRM), dams and mines (geotech), and broad research objectives for environmental systems.
The CR1000Xe is a low-powered device that measures analog and digital sensors, processes and stores measurements, and adapts to any communications link. It stores data and programs in non-volatile flash memory. The onboard programming language—common to all Campbell Scientific data loggers—allows users to create solutions perfectly tailored to the application.
