CR800 Datalogger

Campbell Scientific

The CR800 is a smaller, research-grade datalogger designed for stand-alone operation in harsh, remote environments. It is intended for smaller configurations in which fewer sensors will be measured. Each CR800 reads input from sensors, then transmits the data via a communication peripheral; most sensors and telecommunication devices are compatible. Multiple CR800s can be configured as a network or units can be deployed individually.

Another datalogger, the CR850, is similar to the CR800, but it has an integrated keyboard and display screen for on-site control.

The CR800 consists of measurement electronics encased in a plastic shell and an integrated wiring panel. This datalogger uses an external keyboard/display and power supply. Low power consumption allows the CR800 to operate for extended periods on a battery recharged with a solar panel—eliminating the need for AC power. The CR800 suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.

The on-board operating system includes measurement, processing, and output.
