The CR200 is our lowest-cost data logger. Its input channel configuration and small size is optimal for measuring one or two sensors. When paired with an ENC200 enclosure and the small 16869 battery, the packaged CR200 has a deployment size of only 6 inches by 7 inches. The CR200 is the base model in the CR200 datalogger series. Three related models, the CR206, CR211, and CR216, carry onboard, spread-spectrum radios, and the CR295 is specially equipped for use with the TX312 GOES transmitter.
