[0002] At present, most adiabatic accelerating calorimeters and rapid screening calorimeters cannot effectively mix samples when testing heterogeneous samples, which leads to inaccurate test results.

If the stirring fails during the stirring process, it is difficult to find it. At the same time, the operation of the motor cannot be effectively monitored. Therefore, a magnetically coupled mechanical stirring device for an adiabatic accelerating calorimeter is proposed. Utility Model Content
