Resistance Ratio Temperature Measurement System

The National Institute of Standards and Technology seeks a resistance ratio temperature measurement system through a total small business set-aside solicitation. The system must meet technical specifications including accuracy of 70 ppb and resolution of 10 ppb over measurement ranges from 5-90C, 2-12C, and 0.2-1.2C. Proposals will be evaluated based on technical factors, with price being less important, and must be received by 11:00am Eastern Time on February 14, 2024.

The solicitation is set aside under NAICS code 334516 (Measuring and Controlling Devices Manufacturing) and PSC code 6625 (Laboratory Equipment and Supplies). The single award firm-fixed price contract is for a system to be installed at NIST's Gaithersburg, Maryland campus within 90 days of delivery and integrated into NIST's LabView automation infrastructure to benchmark a photonic thermometer against SPRT standards. The one year warranty system will be paid for at 100% upon acceptance after onsite testing verifies performance meets uncertainties outlined in NIST SP250-81.
