Description

The Department of the National Research Council Canada requires the supply of one air bath to replace the current oil bath system. The air bath must provide a dry, clean, silent, and stable environment for standard resistors, maintaining a precise and uniform temperature essential for accurate resistance measurements in thermometry applications. The system must provide temperature stability of 10 mK or better over 24 hours at 23C, temperature uniformity of 10 mK or better at 23C, operate over a temperature range of +15C to +35C, have an internal volume between 50 L and 120 L, and be CSA approved or equivalent. The system must also be capable of remote control and data extraction via computer interfaces such as RS232, Ethernet, GPIB, or USB.
