Title: Notice of Intent to Sole Source to Process Sensing Technologies
The National Institute of Standards and Technology (NIST) is seeking information from sources that may be capable of providing a chilled-mirror hygrometer. If no alternate sources are identified, the Government intends to issue a Sole Source Award to Process Sensing Technologies located at 135 Engineers Rd, Hauppauge, NY 11788 under the authority of FAR 13.106-1(b); only one source reasonably available. The North American Industry Classification System (NAICS) code for this acquisition is 334513.
BACKGROUND
The National Institute of Standards and Technology (NIST), Physical Measurement Laboratory (PML) Temperature and Humidity Group requires a chilled-mirror hygrometer to perform measurement services for temperature and humidity, including calibration of thermometers and hygrometers.
NIST is developing a high-pressure humidity generator for the calibration of hygrometers at pressures up to 7 MPa. This generator will need a check standard to validate the humidity standards produced by this generator. This project is being pursued to satisfy the needs of customers that need calibration of hygrometers at high pressures, and the generator will be used as part of NIST measurement services. The principal requirement of this check standard is that it measure dew/frost point with the accuracy of a chilled-mirror hygrometer (reproducibility of 50 mK).
General Requirements:
The Contractor shall provide a chilled-mirror hygrometer that meet the following minimum specifications:
The mirror sensor must be contained in a remote head.
The remote head must be able to withstand a pressure up to 7 MPa.
The mirror must have a reproducibility of 0.05 °C.
NIST is seeking information from sources that may be capable of providing a solution that will achieve the objectives described above.
