We design and manufacture a range of dataloggers, from the most basic system with just a few channels, to expandable systems that measure hundreds of channels. Our systems feature wide operating temperature ranges, low power use, and the ability to store a large number of measurements. They can also operate independent of AC power, and human or computer interactions. Most sensors connect directly to our dataloggers, eliminating external signal conditioning. Scan rates can be programmed from a few hours to 100,000 times per second, depending on the datalogger model. Measurement types, processing algorithms, and recording intervals are also programmable. On-board instruction sets contain programmed statistical and mathematical functions that provide on-site data reduction and that output results in the desired units of measure.

Our dataloggers not only provide advanced measurement capabilities, but can also control external devices. Unattended measurement and control decisions can be based on time or conditional events. Phones, pagers, radios, and other devices can be used by the dataloggers to report site conditions.

Because our dataloggers have many channel types and programmable inputs, they can measure most commercially available sensors. Datalogger channel types include analog (single-ended and differential), pulse counter, continuous analog output, digital I/O, anti-aliasing filter, and switched excitation. Multiplexers and other peripherals can be used to increase the number of channels and channel types.

A full line of telecommunications and on-site data storage and retrieval products allow you to retrieve data from the office or in the field. On-site options include direct connection to a PC or laptop, PC cards, storage modules, and datalogger keyboard/display. Telecommunication options include short-haul, multidrop, telephone (including voice-synthesized and cellular), radios (UHF, VHF, and spread spectrum), and satellite.

Campbell Scientific software gives you the option of controlling our data acquisition systems from your computer. Programs are available that facilitate datalogger programming, communications management, and graphical display and analysis of data. For first-time users, free starter software simplifies programming and data retrieval.

With our data acquisition systems at the core, we have developed innovative systems for a variety of applications.

These systems include:

• Weather and climate stations (custom and preconfigured)
• Hydrological stations
• Aquaculture monitoring and control systems
• Pump slug and test systems
• Time domain reflectometry systems
• Trace gas system
• Flux systems
• Bowen ratio systems
