66 -- MEASUREMENT AND CONTROL MODULES, MONITOR AND RECORD, SENSORS, ACCESSORIES AND FIBER OPTIC CABLE SOL RFQ-NC-97-04 DUE 090297 POC Cynthia A. Johnson, Contract Specialist, (612) 649-5203 or Julia A. Byrd, Purchasing Agent, (612) 649-5205. Provide commercial equipment to setup a network of meteorological instruments to measure wind speed, wind direction, air temperature, relative humidity, photosynthetically active radiation, net radiation, precipitation, soil moisture, and soil temperature at numerous locations and heights (depths) within tree stand test plots. A multiplexer/data logger and fiber optics line connecting each instrument will allow the transfer of data stored in all data loggers to a central computer facility at the site where data will be downloaded onto internal or external computer storage devices. These data will then be periodically downloaded via modem or high-speed data transfer line for then be periodically downloaded via modem or high-speed data transfer line for analysis and archiving activities. 17 line items: (1) Measurement and Control ASystem (data logger) with Black Wiring Panel and 128K Memory; Temp.
