Datalogger Campbell CR800

Campbell Sci – CR800

The CR800 is a smaller, research-grade data logger 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.
