CR310 Datalogger

The newest member of our CR300-series dataloggers, the CR310, is now available. It is similar to our CR300 datalogger, except the CR310 is 2.5 cm longer and includes an integrated 10/100 Ethernet port and removable terminals. Its small size and integrated Ethernet port make the CR310 ideal for small applications requiring Ethernet communication.

The CR310 can measure most hydrological, meteorological, environmental, and industrial sensors. It supports serial communication and uses an onboard compiler that can handle large and complex programs. Other benefits include:

  • Ability to measure many 4 to 20 mA sensors natively
  • 24-bit analog-to-digital converter that provides incredible analog measurement accuracy
  • Support for Modbus, DNP3, PakBus, and other popular protocols
  • Ability to send encrypted/secure email messages and alarms (TLS-encrypted SMTP)
  • Integrated charge regulator for directly connecting the battery and solar panel
  • Very modest power budget that allows smaller batteries to power the system for longer time periods
  • Campbell quality surge and electrostatic discharge (ESD) protection

Besides the integrated Ethernet port, the CR310 has several communication options. Three different embedded radio options are available to cover the unique requirements found worldwide. Soon the CR310 will also have a Wi-Fi option that supports short-range wireless IP communication. These communication options, along with the integrated Ethernet port and integrated charge regulator, reduce costs and simplify installation because the system requires fewer additional peripherals.

Campbell Scientific is excited about the CR310. This new low-cost, high-value datalogger promises to be a valuable addition to our CR300-series datalogger family.
