Detailed Description
The CR300 is a low-powered data logger designed to measure sensors, analyze data, and store data and programs. A battery-backed clock assures accurate timekeeping. The on-board, BASIC-like programming language—common to all Campbell Scientific data loggers—supports data processing and analysis routines.
The CR300 wiring panel includes a switchable 12 V terminal, and analog grounds dispersed among six analog terminals.
