66 -- INTEGRATING NEPHELOMETER WITH BACKSCATTER SHUTTER SOL NRMGC3-905054DT DUE 082699 POC Doris Turner, Purchasing Agent, 303-497-3872 or FAX: 303-497-3163 E-MAIL: NOAA; MASC Acquisition Management, Doris.P.Turner@noaa.gov. The National Oceanic and Atmospheric Administration (NOAA) requires a 3 color integrating nephelometer with backscatter shutter, power supply and DOS and Windows versions of software. This instrument is to be mounted on a research aircraft and will provide measurements of the light scattering coefficient due to atmospheric aerosols at three wavelengths. The instrument mount will be either inside the aircraft pressure vessel or within an external pod on an aircraft. This instrument must be rectangular, roughly 45 inches long, 12 inches wide, and 12 inches high. It must weigh less than 50 lbs. The power requirements should be 115 V AC 50-60 Hz for power supply, which is converted by the instrument power supply to 28 V DC less than 5A to run the instrument. This instrument must provide measurements at 3 wavelengths: 450 nm (blue), 550 nm (green), and 700 nm (red) and have a bandwidth of 40 nm for all wavelengths. The sensitivity to red and green wavelengths should be 2.0 divided by 10,000,000 inverse meters. Angular integration should be from 7 to 170 degrees. The instrument should posses a backscatter shutter to provide the ability to change only to backscatter only measurement (angular integration from 90 to 170 degrees). Interested sources proposing to supply the specified nephelometer must submit a written qualification statement clearly establishing capability to meet the above requirements within 15 days from the date of this synopsis. The qualification statements will be used to determine the need for competitive bids. In the absence of other qualified sources, it is the intent of the Government to negotiate a sole source contract under the authority of 41 U.S.C. 253(c)(1) with TSI, Inc., 500 Cardigan Road, St. Paul, MN 55164 as this source is considered to be the only responsible source and no other items will satisfy agency requirements. Responses are due via mail or FAX by August 26, 1999. No RFQ package is available. This procurement is being conducted per Simplified Acquisition Procedures FAR Part13 (NTE $100,000).
