This new product mixer,it adopts a brulshess  DC motor and runs silently.
It suits for general mixing and can handle up to 25L of water.the speed range is 0/30-2000rpm,automatically adjusted by microprocessor control technology.
The safety circuit design can ensure an auto stop when the motot is blocked or overloaded.It can continuously compare the actual speed of the stirring shaft with the set speed and auto adjust the speed devivation to realize constant speed during the experiment.It keeps constant even the the viscosity of the samples changes.
