NIST seeks information from potential suppliers for a specialized blackbody cavity calibration bath with an operating range of -20°C to +130°C, intended for IR thermometer calibrations. The required solution must include three line items: one OB-15/2 BBLT Calibration Bath, one ASTM standard blackbody cavity with a 74 mm opening, and 15 units of silicone oil fluid. The bath must support dry-air purges and use a high heat-transfer fluid to minimize temperature gradients. This is a market research request, not a formal solicitation, and responses should include detailed company and product capability information. No specific budget, performance location, or non-bid/submission timelines are mentioned in the description.
