Overhead Stirrer features stepless speed control and a DC brushless motor, with digital display of operating speed. It is characterized by constant speed and automatic torque adjustment. Its automatic overload and abnormal condition protection to ensure efficient and safe experiments. It is suitable for mixing low to high viscosity liquids or solid-liquid mixtures, and isdely used in chemical synthesis, pharmaceuticals, physicochemical analysis, and other fields.
Features:
- Colorful LCD(320x240 Pixel) displays speed, time and status.
- Stirring paddle “through-shaft” design, easy to adjust impeller position and replace the container.
- Multiple protection: automatically shut down and alarm in the event of overload, short circuit, over-temperature, abnormal speed, etc.u
- Brushless DC motor, low noise, small interference, free maintenance.
- Self - locking drill chuck, tools free.
- Set speed can be maintained when viscosity of liquid changes.
- Directly connect to computer via USB interface for remote control and speed recording.
