DATALOGGER EVALUATION. FINAL REPORT

The results are reported of a study to determine which commercially available portable datalogger was best suited for use in cold temperatures by the Alaska Department of Transportation and Public Facilities. The criteria for selecting the datalogger were: (1) the datalogger must be portable and operate accurately and continuously at cold temperatures; and (2) the datalogger must be easily programmable and data must be easily retrievable. The two dataloggers studied were (1) the Metrosonics d1-721 (8-channel, general purpose, battery-operated datalogger capable of storing over 7,200 values), and (2) the Campbell Scientific 21X (general purpose, battery-operated datalogger/processor capable of storing 768 values, expandable to 19,000 values). The details are described of the test procedure, and the test results are discussed. Appendices detail the specifications of each datalogger.
