This version of the CR800 is for OEMs. The OEM can purchase this product without a label or with a company label.
The CR800 is a smaller measurement and control data logger designed for stand-alone operation in harsh, remote environments. Each CR800 reads input from sensors, then transmits the data via a communication peripheral. Multiple CR800s can be configured as a network or units can be deployed individually.
The CR800's low power consumption allows it to operate for extended time periods on a battery recharged with a solar panel—eliminating the need for AC power. This data logger suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.
A typical field-based CR800 system consists of:
The CR800 is compatible with our measurement and control devices, nearly every available sensor, and most of our communication devices; refer to the Compatibility tab for more information.

With several channel types, the CR800 is compatible with nearly every available sensor, including thermocouples, SDI-12 sensors, and 4 to 20 mA sensors. A custom ASIC chip expands its pulse count, control port, and serial communications capabilities. The CR800's I/O ports can be paired as transmit and receive, allowing serial communications with serial sensors and devices.
The CR800 is compatible with all of our contemporary SDMs, multiplexers, vibrating wire interfaces, terminal input modules, and relays.
The CR800 communicates with a PC via direct connect, NL100 Ethernet Interface, multidrop modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos, High Data Rate GOES, and Meteosat). Data can be viewed on the CR1000KD Keyboard Display, CD295 DataView II Display, Archer-PCon Field PC, or a user-supplied PDA (PConnect or PConnectCE software required).
The SC115 is the only compatible external data storage device. The CR800 does not have a peripheral port and is therefore not compatible with the CFM100, NL115, or NL120.
The CR800 and its power supply can be housed in an ENC12/14, ENC14/16, or ENC16/18 enclosure.
Any 12-Vdc source can power the CR800 datalogger; a PS100 or BPALK is typically used. The PS100 provides a 7-Ahr sealed rechargeable battery that should be connected to a charging source (either a wall charger or solar panel). The BPALK consists of eight non-rechargeable D-cell alkaline batteries with a 7.5-Ahr rating at 20°C.
Also available are the BP12 and BP24 battery packs, which provide nominal ratings of 12 and 24 Ahrs, respectively. These batteries should be connected to a regulated charging source (e.g., a CH100 connected to a unregulated solar panel or wall charger).
CRBasic, the CR800's full programming language, supports simple or complex programming and many onboard data reduction processes. Compatible software includes:
