Overview

Measurement & Control Datalogger (Operating Range -40 to +70C)

The CR350 is a multi-purpose, extremely low-power, compact measurement and control data logger. This entry-level data logger, with its rich instruction set, can measure most hydrological, meteorological, environmental, and industrial sensors. The CR350 concentrates and makes data available over varied networks, with delivery using your preferred protocol. The CR350 also performs automated on-site or remote decision-making for control and M2M communications. This data logger is ideal for small applications requiring long-term, remote monitoring and control.

The following outlines the primary differences between the CR310 and CR350 dataloggers:

The CR310 and CR350 offer removable connectors.
The CR310 includes a 10/100 Ethernet connection.
The CR350 has two independent RS-232/RS-485 ports and USB-C.

The CR350 includes Wi-Fi, cellular, or the following radio options for different regions:

CR350-RF407: US and Canada
CR350-RF412: Australia and New Zealand
CR350-RF422: UK and EU
CR350-RF427: Brazil

Note: Campbell Scientific does not recommend the CR350 for use as a PakBus router in networks with more than 50 devices. Large arrays or string variables may also reach memory limits. For such applications, a CR1000Xe Measurement and Control Datalogger is recommended.

Key Advantages

Compact Data Logger with RS-485
Ideal for small applications

Technical Description

The CR350 is a low-powered data logger designed to measure sensors, analyze data, and store data and programs. A battery-backed clock assures accurate timekeeping. The on-board, BASIC-like programming language—common to all Campbell Scientific data loggers—supports data processing and analysis routines.
