66 -- DOUBLE-SINKER DENSIMETER SOL NB838-801753DT POC Doris Turner, Purchasing Agent, PH: 303-497-3872 or FX: 303-497-3163 E-MAIL: NOAA; MASC Acquisition Management, Doris.P.Turner@noaa.gov. The National Institute of Standards and Technology (NIST) requires a double-sinker densimeter for high accuracy gas density measurements. This device shall be an absolute instrument for the determination of density (meaning that no calibration fluids are required). It shall be capable of operation over the temperature range of -180 degrees C to +240 degrees C and the pressure range of 0 -- 40 MPa. The uncertainty in density shall be +/-0.02% + 0.001 kg/m cubed over the entire temperature and pressure range and +/-0.01% + 0.0006 kg/m cubed over the temperature range of -20 degrees C to +70 degrees C. It shall consist of a magnetic suspension balance capable of contactless force measurements, two calibrated sinkers of matched surface area and surface material, a sinker changing mechanism, and a measuring cell capable of withstanding the stated temperatures and pressures and integrating the magnetic suspension balance, sinkers, and sinker changing mechanism into a compact unit. Interested sources proposing to supply an equivalent system 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 Rubother Prazisionsmesstechnik, Universitaetsstrasse 142, D-44799 Bochum Germany as this source is considered to be the only responsible source and no other items will satisfy agency requirements. This simplified acquisition will be based upon the best value to the Government, with technical merit and past performance being significantly more important than price. Terms and conditions and agency level protest procedures are reference at http://netsite.esa.doc.gov. No RFQ package is available. (0093)
