Overview
The CR1000X is our flagship data logger that provides
measurement and control for a wide variety of applications. Its
reliability and ruggedness make it an excellent choice for
remote environmental applications, including weather
stations, mesonet systems, wind profiling, air quality
monitoring, hydrological systems, water quality monitoring,
and hydrometeorological stations.
The CR1000X is a low-powered device that measures sensors,
drives direct communication and telecommunications,
analyzes data, controls external devices, and stores data and
programs in onboard, nonvolatile storage. The electronics are
RF-shielded by a unique sealed, stainless-steel canister. A
battery-backed clock assures accurate timekeeping. The
onboard, BASIC-like programming language, common to all
contemporary Campbell Scientific data loggers, supports data
processing and analysis routines.
Benefits and Features
Operational in extreme environments with a standard
operating range of -40° to +70°C and an extended operating
range of -55° to +85°C
Connects directly to a computer's USB port
Captures quickly changing data values with fast analog
measurement capabilities (300+ Hz)
Differentiates even slight changes in data values with higher-
resolution measurements (24 bit Adc)
Includes two non-isolated current input channels for directly
connecting sensors with 0-to-20 mA or 4-to-20 mA current
outputs
Contains an onboard CPI port for hosting Campbell high-
speed sensors and distributed modules (CDM)
Directly connects to Ethernet
Includes microSD card drive for extended memory
requirements
Provides simple serial sensor integration and measurement
with SDI-12, RS-232, and/or RS-485
Supports full PakBus networking
Includes embedded web page for direct connection via web
browser
