Campbell Scientific has revealed the latest addition to its CR300-series measurement and control dataloggers. The CR310 has the capabilities of the CR300 but benefits from the addition of removable connectors and an integrated 10/100 Ethernet connection. It is available with optional integrated wi-fi and licence-free radios for wireless networking. Providing complete compatibility with a variety of measurement and communication protocols, the CR310 supports TCP/IP, Modbus, DNP3, SDI-12, HTTP, FTP and email. The first CR300 model was launched in March 2016. Utah-based Campbell Scientific has since released various onboard radio options. According to the company, the CR300 range combines many of the best capabilities of full-size Campbell Scientific dataloggers with the smaller size and price of its compact dataloggers. Among the new and improved features are a much richer CRBasic command set and serial communication capabilities, and the capacity for larger, more complex programmes. The CR300 also has its own onboard compiler. The new dataloggers are the same size as the earlier compact Campbell Scientific dataloggers, making them potential drop-in replacements. They are also the first Campbell dataloggers that can measure 4mA to 20mA sensors natively. The new series has a 24-bit analogue to digital converter, a high-speed processor and a micro-USB port. For communication, the CR300 has full PakBus capability. The series is programmed with Campbell Scientifics LoggerNet software, which includes a point-and-click program generator, and a network planner for graphical layout of devices.
