De CR310 is een multifunctionele, compacte meet- en besturingsdatalogger met geïntegreerde Ethernet-poort. Deze kleine en hoogwaardige datalogger biedt snelle communicatie, lage stroomvereisten, een ingebouwde USB en uitstekende analoge ingangsnauwkeurigheid en resolutie. De CR310 kan de meeste commercieel beschikbare hydrologische, meteorologische, omgevings- en industriële sensoren meten. De CR310 is ook leverbaar met verschillende radio (CR310-RF422) en WiFi opties (CR310-WIFI).
