This entry level datalogger, with its rich instruction set, can measure most hydrological, meteorological, environmental and industrial sensors.
The CR300 is a multi-purpose, compact, low-cost measurement and control datalogger. It will concentrate data, making it available over varied networks and deliver it using your preferred protocol. The CR300 also performs automated on-site or remote decision making for control and M2M communications. The CR300 is ideal for small applications requiring long-term, remote monitoring and control.
The CR300 replaces the CR200, CR200X, CR211 & CR211X. While no longer available, support will still be provided for these earlier models.
There are a range of models available for different communications requirements, including ethernet, Wi-fi, radio and cellular.
