At Campbell Scientific, they manufacture dataloggers, data acquisition systems, and measurement and control products used worldwide in research and industry. Their instrumentation is known for its flexibility, precision measurements, and dependability—even in harsh, remote environments. Since their inception in 1974, they have manufactured approximately 150,000 systems. They continually strive to develop innovative products that meet the needs of their customers.

Products
Campbell Scientific designs and manufactures a range of dataloggers, from the most basic system with just a few channels, to expandable systems that measure hundreds of channels. Their 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 their 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. Onboard instruction sets contain statistical and mathematical functions that provide on-site data reduction and output results in the desired units of measure. Their 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 their dataloggers have many channel types and programmable inputs, they can measure almost any commercially available sensor. 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.

A full line of telemetry 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, PDAs, and displays. Telemetry options include Ethernet, short-haul, multidrop, telephone (land-line, voice-synthesized, and cellular), radios (UHF, VHF, and spread spectrum), meteor burst, and satellite.

Systems and Applications
With their dataloggers at the core, they have developed innovative measurement and control systems for a variety of applications. The open design of their dataloggers makes them useful in a large number of applications including:
