Abstract:An ultra-low temperature adjustable thermostat device with continuously adjustable temperature function was developed, the design principle, specific structure, testing process, and experimental results of the device were described. In order to verify the performance of the device, the experiment of the device temperature volatility, the inter hole temperature uniformity experiment, and the heating rate tests were performed. The results show that the temperature volatility is better than 2mK/10min, the temperature difference is better than 2mK and the heating rate is better than 1.5℃/min. At the same time, the design of the temperature controller was completed, which can realize switching between multi-stage and single-stage temperature control. The developed ultra-low temperature adjustable thermostat device has a temperature range of -180~-60℃ and a temperature control resolution of 0.001K.
