CR310 Compact Data Logger 


The newest member of our CR300-series data loggers, the CR310, is now available. It is similar to our CR300 data logger, 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 data logger promises to be a valuable addition to our CR300-series data logger family.

New Communications Options

As promised, our CR6 data loggers now have the same radio options as our CR300-series data loggers. These radio options are suitable for the following regions:

Embedded Radio Where Used Frequency
RF407 U.S., Canada 902 to 928 MHz
RF412 Australia, New Zealand 915 to 928 MHz
RF422 Most of Europe and some of Asia 863 to 870 MHz

The embedded, license-free radios are a low-cost solution for creating wireless communication links to and between data loggers. The data logger/radio combinations consume little power and are easy to install and maintain.

This option is an ideal solution for short-range wireless IP communications. The CR300-WIFI will come factory-configured as a Wi-Fi access point, but also can be configured to join an existing Wi-Fi network with standard or enterprise (EAP) security.

The radio and Wi-Fi options provide onboard wireless communication capabilities that previously required external peripherals. Reducing the number of additional peripherals not only decreases overall system cost but eliminates the hassle of integrating and installing the peripherals.
