The CR216 datalogger combines an on-board 2.4 GHz spread-spectrum radio with the functionality of the CR200 Datalogger. The CR216 provides both measurement and communication capability in a small, rugged package. The CR216's 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 CR216 has a deployment size of only 6 inches by 7 inches. If an alternate spread-spectrum radio is required, see our CR206 and CR211 dataloggers.
