Campbell Scientific CR800 series data loggers

The CR800 series data loggers are a complete measurement and control system designed to take over from the previous CR510 data logger. The two data loggers are suitable for small to medium long term or remote applications, but with added peripherals can be used in large projects.

The series contains two versions of the logger, the CR800 and CR850. The CR800 has an external keyboard option (CR1000KD), connecting via the CS I/O port, allowing the user to travel to multiple sites, while the CR850 has an in-built keyboard display. By using either the external keyboard or in-built display, users can display stored values, edit programs on site and calibrate sensors.

Both data loggers support the flexible CRBasic programming language, facilitating data processing and analysis routines. PakBus and Modbus RTU communication protocols allow for multiple telemetry options and logger networking. The series also features 2 MB of battery-back SRAM and clock that ensures data, programs and accurate time are maintained while it is disconnected from main power. Unlike its predecessor the CR510, the CR800 series supports multiplexers and SDM devices, allowing users to expand their network without using high end equipment.
