Description

technical field [0001] The invention relates to the field of temperature control, in particular to a medical multi-temperature zone constant temperature controller and a control method thereof. Background technique [0002] In medical scientific research and medical inspection, there are strict requirements for temperature control. For example, the low-temperature storage of pharmaceutical reagents and the constant temperature requirements of test samples all require strict temperature control. How to effectively and quickly regulate and control the constant temperature has important research significance. Due to the wide temperature range required by medical testing instruments, the multi-temperature zone and universal convenience of the constant temperature control system have become the core issues of the design. How to effectively and quickly regulate and control the constant temperature has important research significance. The existing controller has a single functio...
