Overview
The CR1000 is our most widely used data logger. It can be used in a broad range of measurement and control functions. Rugged enough for extreme conditions and reliable enough for remote environments, it is also robust enough for complex configurations. Used in applications all over the world, it will be a powerful core component for your data-acquisition system.
Key Advantages
Multipurpose data logger for monitoring and control
Technical Description
The CR1000 consists of a measurement and control module and a wiring panel. This data logger uses an external keyboard/display and power supply. Low power consumption allows the CR1000 to operate for extended time periods on a battery recharged with a solar panel—eliminating the need for AC power. The CR1000 suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.
The CR1000's module measures sensors, drives direct communications and telecommunications, reduces data, controls external devices, and stores data and programs in on-board, non-volatile storage. The electronics are RF shielded and glitch protected by the sealed, stainless-steel canister. A battery-backed clock assures accurate timekeeping. The module can simultaneously provide measurement and communication functions. The on-board, BASIC-like programming language supports data processing and analysis routines.
The CR1000WP is a black, anodized aluminum wiring panel that is compatible with all CR1000 modules. The wiring panel includes switchable 12 V, redistributed analog grounds (dispersed among analog channels rather than grouped), unpluggable terminal block for 12 V connections, gas-tube spark gaps, and 12 V supply on pin 8 to power our COM-series phone modems and other peripherals. The control module easily disconnects from the wiring panel allowing field replacement without rewiring the sensors.
Originally, the standard CR1000 had 2 MB of data/program storage, and an optional version, the CR1000-4M, had 4 MB of memory. In September 2007, the standard CR1000 started having 4 MB of memory, making the CR1000-4M obsolete. Data loggers that have a module with a serial number greater than or equal to 11832 will have a 4 MB memory. The 4 MB data loggers will also have a sticker on the canister stating “4M Memory”.

Orderable34152
CR1000 Calibration over Temperature and ISO/IEC 17025 Calibration Verification with Certificate
The 34152 provides factory calibration of the CR1000 to meet original specifications, then sends the calibrated data logger to be verified by a certifying body that is accredited to the ISO 17025 standards.
Orderable
This service requires an RMA (Return Material Authorization) from Campbell Scientific. The factory calibration includes comprehensive testing of all data logger functions over its standard temperature range (-25° to +50°C) and the replacement of the internal lithium battery and desiccant packs. During testing, the data logger’s operating system is updated, and all settings are restored to factory defaults unless otherwise requested. Upon completion of the factory calibration, the data logger is sent to the ISO 17025 accredited certifying body referenced above for calibration verification.
Compatibility
Sensors
With several channel types, the CR1000 is compatible with nearly every available sensor, including thermocouples, SDI-12 sensors, and 4 to 20 mA sensors (via a terminal input module, such as the CURS100). A custom ASIC chip expands its pulse count, control port, and serial communications capabilities. The CR1000's I/O ports can be paired as transmit and receive, allowing serial communications with serial sensors and devices.
Measurement & Control Peripherals
The CR1000 is compatible with all of our CDMs (requires an SC-CPI), SDMs, multiplexers, vibrating-wire interfaces, terminal input modules, and relays.
Communications
The CR1000 communicates with a PC via direct connect, Ethernet interfaces, multidrop modems, short-haul modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos, Iridium, and Inmarsat).
Data can be viewed on the CR1000KD Keyboard Display, the CD100 Mountable Display with Keyboard, an iOS or Android device (requires LoggerLink), CD295 DataView II Display, or a user-supplied PDA (PConnect or PConnectCE software required).
Compatible external data storage devices are the CFM100, NL115, and SC115.
Enclosures
The CR1000 and its power supply can be housed in any of our standard enclosures.
Power
Any 12 Vdc source can power the CR1000 datalogger. Power supplies commonly used with the CR1000 are the BPALK, PS150, and PS200. The BPALK provides eight non-rechargeable D-cell alkaline batteries with a 7.5 Ah rating at 20°C.
Both the PS150 and PS200 consist of a sealed rechargeable 7 Ah battery and a charging regulator. Their battery should be connected to a charging source (either a wall charger or solar panel). These two power supplies differ in their charging regulator. The PS150 has a standard regulator and the PS200 has a micro-controller-based smart regulator. The PS200's regulator provides two-step constant voltage charging and temperature compensation that optimize battery charging and increases the battery’s life.
Also available are the BP12 and BP24 battery packs, which provide nominal ratings of 12 and 24 Ah, respectively. These batteries should be connected to a regulated charging source (e.g., a CH100 or CH200 connected to a unregulated solar panel or wall charger).
Software
CRBasic, the CR1000's full programming language, supports simple or complex programming and many onboard data reduction processes.

- OS and FirmwareCR1000 OSv32.07
May 15, 2024
Execution of this download installs the CR1000 Operating System and Compiler on your computer. It also updates the CR1000 support files for the CRBasic Editor. Note: This OS has crossed the 2 Meg CR1000 size limit for remote download. The OS must be downloaded to the 2 Meg CR1000 via direct connect with the Device Configuration Utility. All OS download methods are supported by the 4 Meg CR1000. Upgrading from versions prior to version 28 of the Operating System will reset the datalogger’s CPU drive. This is due to a change in the format of the file system from FAT16 to FAT32. In order for the datalogger to operate correctly, as part of the upgrade, the CPU drive is formatted to FAT32. Any programs stored and running from the CPU drive will be lost. It is not recommended to update the datalogger’s Operating System over a remote connection where program control regulates the communication equipment (turning it on or off, etc.). In these cases, an on-site visit and a backup using DevConfig’s backup utility is necessary to update the datalogger’s Operating System. Watch the Video Tutorial: Sending an OS to a Local Datalogger. In all cases where the datalogger is being updated from an Operating System prior to 28, the use of DevConfig’s backup utility is recommended due to the CPU drive being formatted using the new FAT32 format.
