Air Bath for Standard Resistors

The National Research Council of Canada is procuring a single air bath system to replace its existing oil bath, ensuring a dry, clean, silent, and thermally stable environment for precision standard resistors used in thermometry applications, particularly for calibrating standard platinum resistance thermometers. The system must maintain temperature stability and uniformity of ±10 mK or better over 24 hours at 23°C, operate within a temperature range of 15°C to 35°C, and feature an internal volume between 50 and 120 liters with a set point resolution of 0.01°C or better. Remote control and data extraction are mandatory through standard interfaces such as RS232, Ethernet, GPIB, or USB, and the unit must be certified by CSA or an equivalent Canadian safety standard. The procurement is conducted as a sole-source award under subsection 6(d) of the Government Contracts Regulations, with Measurements International identified as the only capable supplier. Other vendors may submit a Statement of Capabilities by August 4, 2026, to challenge the sole-source determination, but must demonstrate full compliance with all technical requirements. Delivery is required by January 1, 2027, to the NRC’s facility in Ottawa, Ontario, and acceptance will occur upon verification of compliance at the delivery site. No contract value, pricing, or payment details are provided, and the solicitation does not include formal evaluation factors, weights, or contract clauses under the Federal Acquisition Regulation. The procurement is exempt from international trade agreements, and all submissions must be directed to Tamara Stabb, Procurement Officer, via email or written correspondence.
