I have a number of these available, all in Excellent condition. These were purchased for a large monitoring project that only lasted a few months and they have been sitting since then.

They have been tested, and include a warranty (30 days from date of sale). Each CR800 has a new internal (3.0 vdc) lithium battery, been updated with the latest Campbell Operating System (CR800.STD.32.05), and a new desiccant pack. The Datalogger has been tested and certified to be working within the original factory specifications of ±0.1% of the full scale range. The testing process and certification is critical for accurate measurements, and credible, reliable data. Each logger will ship with a Bench Status Report (see images).

These loggers are ready to be deployed. I have Campbell Scientific power supplies and other related equipment listed in separate auctions. Additionally, I have a wide variety of related items that have not been listed. If you need any other sensors, power supplies, software, communications equipment or anything else to complete your data collection system, please ask, I may be able to assist. You will receive a shipping discount when multiple items can be combined.

Detailed Description

The CR800 consists of measurement electronics sealed in a stainless steel enclosure, which is encased in a polycarbonate integrated wiring panel. This data logger can be used with an external keyboard/display and power supply. Low power consumption allows the CR800 to operate for extended periods on a battery recharged with a solar panel—eliminating the need for AC power. The CR800 suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.

The on-board operating system includes measurement, processing, and output instructions for programming the data logger. The programming language, CRBasic, uses a BASIC-like syntax. Measurement instructions specific to bridge configurations, voltage outputs, thermocouples, and pulse/frequency signals are included. Processing instructions support algebraic, statistical, and transcendental functions for on-site processing. Output instructions process data over time and control external devices.

Benefits and Features
Ideal applications include wind profiling, weather stations, ETo/agriculture, air quality, soil moisture, water level/stage, aquaculture, vehicle testing, Time Domain Reflectometry, SCADA, and water quality applications.
Simple in design, the CR800 is easier to program and wire.
Serial communications with serial sensors and devices supported via I/O port pairs.
Contains custom ASIC chip that expands pulse count, control port, and serial communications capabilities.
Compatible with channel expansion peripherals allowing you to expand your system.
Supports PakBus, Modbus, SDI-12, and DNP3 protocols.
Includes both an CS I/O port and an RS-232 port for connecting communication devices.
Gas Discharge Tube (GDT) protected inputs.
Battery-Backed clock to ensure accuracy even if the logger is disconnected from power.
Programable with LoggerNet, PC400, or Short Cut to fit your setup.
