Constant temperature heating refers to the process of heating the object to be heated at a constant temperature. In this process, the system constantly monitors the temperature of the object and makes adjustments according to the monitoring results to keep the heating temperature stable. Constant temperature heating system usually consists of temperature monitoring equipment, heating equipment and controller.

Constant temperature heating is widely used in biotechnology, medical equipment, chemical laboratories and other fields. In biotechnology, for the sample container that needs constant temperature heating, the system can control the surface temperature of the sample through constant temperature to ensure the accuracy of the experiment. In the field of medical devices, constant temperature heating can be used to treat some abnormal symptoms on the body surface, such as muscle pain and ligament injury. In the chemical laboratory, constant temperature heating technology can be used to study the reaction of some compounds to produce cells or other complex substances.

The advantage of constant temperature heating is that it can ensure the continuous reaction of the sample at constant temperature, thus avoiding the experimental error caused by temperature fluctuation. Its disadvantage is that it needs a complex control system to ensure that the constant temperature can be accurately monitored and controlled. In some cases, constant temperature may also lead to uneven reaction rate, thus affecting the experimental results. Therefore, it is necessary to scientifically analyze and improve the constant temperature heating technology in practical application.
