CR310-WiFi Datalogger with Ethernet

The primary differences between the CR300 and CR310 are that the CR310 offers removable connectors and a 10/100 Ethernet connection.

The CR310 has multiple radio options that are suitable for different regions:

CR310-RF407: US and Canada
CR310-RF412: Australia and New Zealand
CR310-RF422: Europe

Compatibility

The CR310 is typically not used with measurement and control peripherals because of its limited number of control ports. It is also compatible with low on current and voltage solid-state relays.

The CR310 is not compatible with SDM or CDM devices.

Sensors

With several channel types, the CR310 is compatible with nearly every available sensor. This includes analog output voltage (0 to 2.5 V) and current (0 to 20 mA or 4 to 20 mA) sensors, thermistors, and RTDs to name a few. It is also compatible with pulse or frequency output sensors such as anemometers, rain gauges, and flow meters. SDI-12, Modbus, and other serial sensors are supported with the RS-232 port and C1 and C2 as a Tx/Rx pair. The CR300 does not directly support RS-485 sensors.

Communications

The CR310 can communicate with a PC via its USB port. Compatible telemetry devices include our RS-485 converters, digital cellular gateways, RF telemetry, and satellite transmitters. Data can be viewed on an iOS device, an Android device, or CD295 DataView II Display.
