Campbell Scientific CR800 Data Logger

The CR800 is engineered for stand-alone operation or networked deployments, making it suitable for field-based monitoring systems. It collects data from connected sensors, processes the information internally, and transmits it through various communication interfaces.

Although now discontinued and replaced by newer models, it remains widely used in legacy systems due to its durability and versatility.
